Looks like someone certainly showed off their Laker pride this weekend!

Zac Efron was spotted sporting a Kobe Bryant t-shirt and Lakers hat on his way to the Staples Center on Saturday to see his favorite team take on the Denver Nuggets in their Game 7 match-up.

Fortunately for him and other Laker hopefuls, the team won in thrilling fashion 96-87 and will move on to the next round of the playoffs to face the Oklahoma City Thunder. Kobe should thank Zac for the star power!

Introducing baby Kelley!

Katherine Heigl and musician hubby Josh Kelley celebrated Mother's Day with a gathering of friends and family in Los Feliz, and we caught our first glimpse of the couple's newly adopted daughter... well, she was hidden under a pink blanket in a bassinet, but still!

The Knocked Up star's oldest daughter Naleigh was all dressed up for the occasion, and her mama followed suit in a pretty spring sundress with thigh high boots. The 33-year-old actress is living proof that you can be a mom and still dress sexy!

How cute is Mr. Kelley?! He really seems to love fatherhood, and we always love seeing a man who isn't afraid to be hands-on.

Izzy is one lucky lady!

What a wonderful way to spend your Sunday!

Ben Affleck and Jennifer Garner attended daughter Violet's ballet recital yesterday, and the happy family left baby Samuel with the nanny and spend the first half of the day with their darling daughters. Jen carried out a beautiful bouquet of flowers, and Ben was on hand to snap pictures of the family outing.

Not only is Violet kicking butt at karate, but it sounds like she's quite the accomplished dancer too!

Forever a wild girl, Rihanna's getting really wild in her upcoming music video for "Where Have You Been." The singer is topless, with painted crocodile scales on her chest and back and she's writing around in the water and ... whew! You've just gotta see it for yourself!

The 24-year-old posted these behind-the-scenes pix (check out our HUGE gallery below) on Facebook Sunday.

Rihanna said of the dance-heavy clip, "I was never going to shoot this video if I couldn't do the choreography. Because it would be pretty pointless. It would be disappointing." "Where Have You Been" is the fifth single from the album Talk That Talk ... check it out!

Simon Cowell's doing something right!

The head honcho at The X Factor just signed on Demi Lovato as the fourth and final judge on the talent show, according to an E! News source.

Lovato will join Simon, L.A. Reid and Britney Spears at the judges' table when the show returns in September.

Fox won't comment on the news, neither will X Factor peeps, but reports claim Spears will get $15 million for a single season.

Cowell fired his frenemy Paula Abdul and Pussycat Doll Nicole Scherzinger in January, after the show's ratings were considerably below American Idol.

Gwen Stefani and Gavin Rossdale took son Kingston for lunch in Koreatown on Sunday for Mother's Day.

Gwen and the kids frequent Little Tokyo for Japanese food and occasionally head to Chinatown for dim sum ... the family enjoys Asian cooking, and who can blame them!

Gavin Rossdale held on tight to his lady's hand and even bought her roses, amid rumors the couple had hit a rough patch in their marriage. The two haven't been together often, as of late, but Gavin has been on the road in support of his new Bush album ... and it ain't over yet! The band will be on the road through the end of the summer, heading to Europe in August.

It's a tough life, but somebody's got a be a rock star!

P.S. We love love love Gwen's Express denim jacket and these houndstooth Paige Denim pants ... so simple, yet so stylish!

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.

Jennifer Love Hewitt got her Mother's Day weekend started with a big boost of java!

The I Know What You Did Last Summer star looked fresh-faced and beautiful as she stopped to pick up coffee for her mom in Burbank, before taking her out to lunch, on Saturday afternoon.

Despite suffering a bit of embarrassment when she confessed her crush on Adam Levin, who then called her "aggressive," the 33-year-old brunette beauty has been enjoying much success from her new Lifetime TV show, The Client List.

The series, based on Hollywood madam Heidi Feliss, is the network's most-watched program since Drop Dead Diva in 2009, and it's recently been renewed for a second season. Congrats, J. Love!
