Jennie Garth's recent split from hubby Peter Facinelli, and her newfound reality show, have thrown the Beverly Hills 90210 star back into the spotlight!

The newly single actress looked cool and casual in a brightly-striped sweater and jeans while causing a mini frenzy after exciting Villa Blanca, in Beverly Hills -- sans wedding ring!-- on Monday afternoon.

Garth is gearing up to have her marital struggles documented on the upcoming CMT reality show Jennie Garth: A Little Bit Country, and last week the actress told ET of her new venture: "Being out here on my own with the girls is not going to be easy, but I know it's the right thing for us right now. I feel it in my heart. I'm excited about what's next."

It's been reported that the couple ended their 11-year marriage over the Twilight star's rumored infidelity, but their rep strongly confirms a "third party" is not to blame for the split. Garth also shared via Twitter this week, "I just want to say to all my fans & friends Thank you for the love and support during this difficult time Dont believe everything you read."

Love is definitely in the air for Amanda Seyfried!

The Lovelace star embraced the first day of spring in a pair of flowered tights and a sheer white top as she ran a few errands in Beverly Hills, on Monday afternoon -- but where was new BF Josh Hartnett?

The hot new Hollywood pair had been keeping their relationship under wraps for several weeks, but finally decided to reveal their status while shopping for groceries together in Hollywood last weekend.

Amanda and Josh picked out yogurt, tortilla chips, cereal, juice and bread at an LA-area Trader Joe's. Since the couple are reportedly shaking up, could house hunting be next on the list?

She may have given birth just a few months ago, but Beyonce is already back to her stunning pre-baby physique!

The busy new mom tore herself away from baby Blue Ivy for a few hours to attend a fancy fundraising event hosted by First Lady Michelle Obama, at the Greenwich Hotel in Manhattan, on Monday night, but Baby Blue wasn't far from her mom's heart!

Queen B chose a blue-inspired ensemble for the outing, wearing a navy blue figure-hugging dress by Victoria Beckham, paired with some serious bright blue bling and blue stilettos -- even her fingernail polish was blue!

President Obama was unable to attend the night's festivities which cost the attendees upwards of $2,000 a head, but First Lady Michelle Obama was there to take over the hosting duties, and she looked understated-chic in a green jacket and black bellbottom pants. Robert De Niro and his wife, Grace Hightower also attended the fundraiser, which will donate all proceeds to Obama's re-election campaign.

Alyson Hannigan showed off her growing baby bump in a dark blue sweater, plaid mini skirt and black tights while on a girls-only shopping trip with daughter Satyana in Santa Monica, on Monday afternoon.

Hannigan has had a very busy month promoting the upcoming flick American Reunion, while also planning a joint birthday celebration with her adorable 3-year-old -- they both share March 24 birthdays!

The How I Met Your Mother star recently told Celebrity Baby Scoop on her big bday plans, "I've been trying to figure out the best birthday party, but I think we might actually just do a trip to Disneyland with a few close friends instead of a big party. I think that would be really special for her and for all of us."

Paris Hilton is off to Florida for concerts and some fun in the sun, and before hopping on the plane this morning, she tweeted, "On my way to Miami with @NickyHilton & @CamRaFace. #GoodTimes ahead ... Ultra & WMC are going to be sick! #YES!" Can't wait for her to post some sexy Twitpics once she lands ... and you know she will!

Paris' pal, DJ Afrojack will be spinning at the Ultra Music Festival on Friday and at Miami hotspot Mansion on Saturday, so we know where to find her!

P.S. That red sweater? Loves it!

Ashton Kutcher is leaving Earth! And no, it's not an effort to escape Demi Moore...

The Two and a Half Men star has signed up to be the 500th "astronaut customer" that will blast into space aboard Virgin Galactic.

"I gave Ashton a quick call to congratulate and welcome him. He is as thrilled as we are at the prospect of being among the first to cross the final frontier (and back!) with us and to experience the magic of space for himself," Virgin CEO Richard Branson announced on his blog Monday. The date of Kutcher's flight has yet to be announced.

It is estimated that tickets for the trip cost around $200,000. Pricey! If recent reports claiming Demi wants Ashton back are true, we wouldn't be shocked if the 49-year-old actress suddenly takes up an interest in space exploration!

Justin Bieber covers Complex's 10th anniversary issue, and not only is the 18-year-old pop star getting socked in the face for this photo shoot, but he opens up about some very adult issues in his interview with the mag.

On his relationship with Selena Gomez:

“There’s no way to hide the relationship completely, because then it would be unfair to us. It’s like, ‘You take this car, and I’ll take this car, and then we’ll meet up at the spot. Then, you go in this door, I’ll go in this door. We’ll end up crossing ways. You get back in this car. We’ll cross over, do a James Bond. You go through the kitchen. I’ll go through the back area. Then we’ll meet in the dressing room and see each other.’ At that point, it’s not even a relationship. You’re just hiding from everyone. That’s unfair and unhealthy, man.”

On the paparazzi:

"I’ll be covering my face and it pisses me off so much when people say, 'Get over it, Justin. You’re famous. People are going to take your picture. Suck it up, you’re rich…' It’s like, 'Yo, I just got off an eight-hour flight. I’m tired and my eyes have bags under them. I’m not trying to take pictures. I’m not going to come to your house, wake you up, and start snapping your picture.'"

Justin may not be wearing a purity ring, but he it sounds like he does have a strict policy when it comes to drugs. Scooter Braun, Justin’s manager, recalls a conversation the two had about drugs recently, and he tells the mag, "[Justin] called me and said 'Do you know why I’m never going to do that stuff? Because I know you’d walk in and beat the sh*t out of me.'"

So what's with the boxing-themed cover shoot? Bieber's father is a former MMA fighter, and the "Boyfriend" singer is a big fan of the boxing champ Floyd Mayweather Jr. Check out the video below for more behind-the-scenes footage of the Biebs, and click thru to see his alternate cover shot!
