Former Disney darlings Vanessa Hudgens and Ashley Tisdale are inseparable.

The besties and their musician beaus went on a double date yesterday to the Myspace party in Hollywood. Ashley and her boyfriend Christopher French sported matching black leather jackets for the event at El Rey Theatre. She wore her signature Daisy Dukes with a floral off-the-shoulder blouse and red booties, while he donned black jeans and a Rolling Stones tee. Vanessa and Austin Butler also kept it casual in jackets and cropped pants.

Other celebrities in attendance included Justin Timberlake, who hosted the event, Miley Cyrus, Kelly Osbourne, Olivia Wilde, Leona Lewis, and Tallulah Willis. The new and improved Myspace relaunched yesterday under Justin and his team's (Specific Media co-founders Chris and Tim Vanderhook) direction.

Ashley Tisdale and boyfriend Christopher French went for a walk in Toluca Lake over the weekend, and after about 7 months together, these two are still going strong! In fact, we never snap these two apart from one another -- looks like the honeymoon phase of their relationship is still going!

"Let 'em wonder how we got this far ... Cause I don't really need to wonder at all #stillintoyou," the 27-year-old actress on Saturday. Hmmm, trying to tell us something?

After ending her two-year relationship with director Scott Speer in late 2011, Ash briefly dated Boys Like Girls lead singer Martin Johnson, but then she got back together with Speer in 2012, only to split from him again late last year. Maybe this guy's the one?

California girls, they're unforgettable.

Vanessa Hudgens and Ashley Tisdale celebrated Memorial Day in true California girl style ... with barbecue and bikinis. The former Disney darlings bared their bods and showed off their taut tummies in swimwear. Ashley even donned Daisy dukes with a bikini on top. Judging by their Instagram photos, it's not hard to see why Ashely was voted number seven and Vanessa number nine on Maxim's Hot 100 list.

Both of the girls wore shades and bikini tops with high-waisted bottoms. Ashley donned a red and white striped bandeau and white denim shorts, while Vanessa sported a pattered bikini and matching kaftan with a black maxi skirt and a black trilby.

The girls, who first met on the set of High School Musical back in 2005, refer to one other as their "twin sister."

Although they're often in the running for the same roles, Ashley told Us Weekly that she never competes with her BFF.

"I call her my twin sister," Ashley told the mag. "She's always there for me. Some people are really competitive; we're not. We're really supportive of each other. You don't find that a lot in this business."

Vanessa also said that their friendship is invaluable.

"We were never competitive in any way, shape or form," Vanessa concurred. "We completely understand each other. She's a lot of fun, and she's just grounded."

Ashley Tisdale and her boyfriend Christopher French are spending every waking moment together, according to our photos ...

The edgy pair made a grocery run early Saturday morning and late took the 'Tis' dog Maui for a "walk" (he mostly cuddled in her arms except for a few pee breaks).

The Disney star and her Annie Automatic musician man have been dating since late last year. She said, recently, that communication is the key to relationships:

"'I'm definitely old-school when it comes to dating. I'm not into the 'game' so much. If I like you, I'll confront you and be open about it. Then I expect you to come after me. Communication is so key. Especially in this business, I'm always traveling and doing something else. So I think communication is the foundation of it all."

Clocking in at 24 hours together non-stop -- that's a LOT of communication!

Oh, the woes of social networking!

One of Ashley Tisdale's followers tweeted her almost 19,000 times since November and recently showed up to her home, TMZ reports.

The Los Angeles Police Dept. is now investigating the matter. They have reportedly identified a suspect, but have yet to determine whether he poses a threat. It's also unclear whether the fan, who's believed to be male, made contact with the actress, but his bizarre comments allude to an ongoing relationship.

Here are some of the tweets:

"My body is yours & even as friends I f***in love how I make u feel like mom maybe we both got issues cuz nobody's perfect."

"Let it all out on me u can have my heart put a lock on it throw away the key & my soul is yours to keep."

Now that's unsettling!

Ashley's reps have not responded to requests for comment.

Disney sure knows how to pick leading ladies!

Former child stars Selena Gomez, Ashley Tisdale, and Vanessa Hudgens joined Miley Cyrus (who already leaked the news that she was crowned No. 1) on Maxim's Hot 100 list.

"It feels amazing to be No. 1," Miley told Maxim about the honor. "Especially because it was voted on by the fans. I have the best fans in the world!"

Selena, who definitively shed her good girl image with her film Spring Breakers and music video for "Come & Get It," nabbed the number two slot. Justin Bieber better hold on tight this time around.

Rihanna, Mila Kunis, Jennifer Lawrence, Jennifer Love Hewitt, Kate Upton, and Elisha Cuthbert rounded out the top 10. Notre Dame football star Manti Te'o's fake girlfriend and Today anchor Hota Kotb also made surprise appearances on the list.

Here are the top 10 girls:

No. 1: Miley Cyrus

No. 2: Selena Gomez

No. 3: Rihanna

No. 4: Mila Kunis

No. 5: Jennifer Lawrence

No. 6: Jennifer Love Hewitt

No. 7: Ashley Tisdale

No. 8: Kate Upton

No. 9: Vanessa Hudgens

No. 10: Elisha Cuthbert

Ashley Tisdale wasn't wearing any makeup and she wasn't exactly in the mood to have her photo taken yesterday, but we did get a glimpse at her flat, tan abs!

The former High School Musical hottie is back from her friend's destination wedding in Cabo San Lucas, Mexico, and she was seen getting quite cozy with beau Christopher French during the trip.

Those two have been dating for about 6 months now, so we have to wonder what's next for them...it's too soon to talk about wedding bells, but maybe a summer engagement?

Ashley Tisdale went to the studio on Tuesday afternoon, and she brought along her adorable pup Maui!

Ash wore a wild pair of leopard pants, and we have to say, it looks like rocker beau Christopher French is having an influence on her wardrobe. The two stepped out at the Scary Movie 5 premiere last week, but she tweeted some song lyrics the other day that make us wonder what's going on in their relationship.

"I should be over all the butterflies, but I'm into you. And baby even on r worst nights I'm into you," Ash wrote, which is from Paramore's song "Still Into You," and later she added a few lines from Calvin Harris and Ellie Goulding's song and tweeted, "I need your love. I need your time. When everything's wrong you make it right."

Maybe she's just on a new music kick?
