Mary Jane the dog, that is!

Miley Cyrus and her hunky boyfriend Liam Hemsworth were snapped taking her new pooch for a walk in Studio City on Sunday, and Miley was still all dolled up from breakfast with her mom Tish.

Earlier in the day Miley tweeted, "Time to deliver breaky in bed with a side of jewelry to the hottest mama in town," and we also snapped the whole fam out and about in the valley. Between Miley, Trace and Brandi, Braison and Noah, we're guessing Tish was spoiled rotten yesterday!

Miley Cyrus has a lot to celebrate this Mother's Day, because she's just become the proud new mom of yet another adopted pooch!

The former Disney star and her sexy man, Liam Hemsworth, took an early morning stroll with the cute black and white pup, who Cyrus ironically named Mary Jane, before she left to celebrate the day with her mom, Tish.

Cyrus shared via Twitter, "time to deliver breaky in bed with a side of jewelry to the hottest mama in town," before sharing a Twitpic of their low-key Mom's Dad brunch.

Even cuter are the pix Miley's been Tweeting. Check 'em out in the gallery below ...

Miley's got a nose ring!

Little Miss Hannah Montana is all grown up, folks, and she's bent on proving it to us! The actress showed off a tiny stud in her nose in a Twitpic back in 2009, but the piercing seems to have been dormant the past few years. Guess Miley's bringin' it back!

Miley and boyfriend Liam Hemsworth enjoyed a fun-filled shopping day date at American Apparel in Studio City, on Thursday afternoon, to have a "basic tee shopping spree," according to the actress' Twitter.

The former Disney star looked hippie-chic in a flowered silk kimono top, jeans, a white tank and round sunglasses, while her hunky Aussie took the opportunity to show off his bulging biceps in a tight yellow tank, paired with jean shorts.

Cyrus' latest film LOL may be tanking at the box office, but at least she's still got the Hunger Games hottie on her arm!

Miley Cyrus is the luckiest girl in the world, and it's not just because she's a 19-year-old multimillionaire and international superstar!

The girl's got hunky Liam Hemsworth all to herself, and he's quite possibly one of the hottest stars in Hollywood right now ... along with his older brother Chris, of course!

The 22-year-old Aussie actor looked fit and fabulous as he flexed huge muscles in a tiny tank while on the way to a friend's house in LA, on Tuesday afternoon -- but he only has eyes for Miley!

The Hunger Games star recently gushed to Details mag, "She makes me really happy. When you start, you want to be professional, but when you're filming those scenes with someone and pretending to love them, you're not human if you don't feel something." Aww!

Taking a break from promoting The Hunger Games world wide, Liam Hemsworth looked effortlessly sexy in a flannel and jeans, while heading to a grocery store with his boys on Friday afternoon.

Miley Cyrus' sexy beau has no problem landing jobs these days, but before he started acting, he was a horrible worker!

The Australian-born actor recently confessed, ''I've done a billion different jobs. I worked for Luke laying carpets for six months, but I'm not a good worker, though. I don't like early mornings. I'd get up and be grumpy, while he's (Luke Hemsworth) more of a wake-up-at-the-crack-of-dawn kind of guy and he's buzzing at 6am. I'm more like, 'Don't even talk to me!'''

Aside from working for his brother Luke, the 22-year-old was also a pet sitter and a bowling alley attendant.

He added, ''I've done laboring jobs, digging holes, I've worked in a bowling alley. I've been a baker. I've been a park ranger for animals. I did almost every job you could do on Phillip Island."

Some lucky lady is about to get a fabulous surprise, courtesy of Liam Hemsworth!

Miley Cyrus's sexy BF stopped into Chelsea's Flowers in Beverly Hills for a fresh bouquet, before popping into Chanel to pick up a little something special, on Tuesday.

While the goodies could be for Miss Cyrus, we're guessing they're actually for Miley's big bro Trace and his girlfriend, Social Network star Brenda Song. It was reported Tuesday Cyrus and Song are expecting their first child together, so what better way to celebrate than flowers and Chanel?

If the rumors are true, Miley will be the coolest aunt ever!
