When it comes to dressing up for Halloween ... Lady Gaga seems to believe that less is definitely more.

The 26-year-old "Born This Way" songstress, who covered her breasts with a couple of sparkly cannabis leaves, Tweeted the above photo and the following:

"I was weed for Halloween. Best costume ever! It's so fun. Princess High the Cannabis Queen."

Back in September, Gaga talked about gaining 25 pounds over the past year. By the looks of those toned abs, seems as though Lady G has slimmed down!

This is quite the outfit!

Lady Gaga stepped out in NYC last night for the opening of the Versace store in Soho, and the singer donned a fuzzy skirt and matching hat. Even though she was showing midriff, she looked more covered up that usual!

Mother Monster has enjoyed a steady relationship with boyfriend Taylor Kinney for some time now, and the Grammy winner has been playing the role of supportive partner as her beau promotes his new TV show Chicago Fire.

"I think she's proud of, you know, a girlfriend being proud of her boyfriend. She's been to the set a couple of times," Kinney revealed on The Today Show.

Gaga finally landed a good one!

At first glance it appears as though Lady Gaga is going for the old school glam look, but take a look at her gold rings and nail jewelry ... she certainly knows how to make a statement!

Gaga greeted fans and posed for pictures outside of Harrods in London on Sunday, and she was on hand to celebrate the release of her debut perfume, Fame. On her way to the department store, Gaga tweeted, "Just drove though London, so beautiful seeing all the Sunday strollers in love..." Um, is she mellowing out on us?! And is it just us, or have the 25 pounds she claims to have gained seemingly slipped off again? Or maybe she's just wearing some really tight Spanx?

In other Gaga news, the pop star pulled a Justin Bieber during her concert in Barcelona on Saturday evening, throwing up three times while she performed "Edge of Glory." She later tweeted a YouTube clip of the incident and wrote, "Was praying nobody saw but actually it's quite a good laugh if you need one! Check out Lady PukeGA doing Swan "Vomit" Lake."

Lady Gaga and the one-and-only Donatella Versace got frisky on a hotel balcony in Milan. Talk about a blonde ambition!

The "Born This Way" songstress brought along plenty of revealing outfit changes, and wigs, for her fashionable trip to Italy.

We're not surprised Gaga's fans went wild when these two shared very public kisses. See more of the two fashionistas playing it up for the cameras in our gallery below.

Lady Gaga is wearing just her undies to promote her new campaign "A Body Revolution."

The "Born This Way" singer posted the above photos on her Little Monsters website and revealed that she's been struggling with "bulimia and anorexia since I was 15."

Gaga said she started the campaign "to inspire bravery and breed some motherf**king compassion."

As Madonna would say ... "Strike a pose (in your yellow underwear), there's nothing to it..."

Before performing at the TUI Arena, Lady Gaga posed for photos with her fans outside of her hotel in Hanover, Germany.

The singer is always making the headlines for something, and this week it's because of her notable weight gain. Though it seems to us like she only put on about five to ten pounds, Gaga told radio host Elvis Duran that she had gained a whopping 25 pounds before her tour started.

“She has no intention of going on a diet or hiding under baggy clothes until she loses some weight,” a source close to Gaga tells The Huffington Post. “That just isn’t her style. She tells her fans to love themselves and that is something that she doesn’t just preach.”

Just when you thought her outfits couldn't get any more outrageous!

Lady Gaga was spotted in a wacky pink and blue get up, complete with electric blue platform boots and a pair of bizarre sunglasses, on the way to her concert in Paris on Saturday. Could she be attempting to hide her fuller figure?

The Mother Monster has been under some scrutiny for her newfound weight gain, hence the reason for her bizarre outfit that resembled an over-sized fat suit. Despite putting on the extra lbs., it seems her fans still have love for the 26-year-old entertainer as her new perfume Fame has reportedly sold 6 million bottles in a week. Congrats Gaga!

You're still looking good Gaga!

Yesterday, the Mother Monster was spotted wearing a tight leopard print outfit and sporting a vintage 'do while stepping out of her hotel in Paris.

The 26-year-old entertainer has been in headlines recently for gaining 25 lbs. but has recently revealed that she's planning on shedding the extra weight, but not for vanity purposes.

"I'm dieting right now, because I gained, like, 25 pounds," Gaga told radio host Elvis Duran. "And you know I really don't feel bad about it, not even for a second. I have to be on such a strict diet constantly. It's hard because it's a quite vigorous show, so I tend to bulk up, get muscular, and I really don't like that. So I'm trying to find a new balance."
