Hilary Duff sure is one fashionable mama! And son Luca's adorable "Hello Ladies" tee is so fetch!

Hilary and her little boy were snapped leaving a mommy and me class in the valley on Wednesday, and she recently revealed that she dropped a whopping 30 pounds after giving birth 11 months ago. Hil and hubby Mike Comrie attended the PGA Tour Wives Association 25th Anniversary Event on Monday, and she revealed to Us Weekly that her trainer Gabe Johns has helped her "lose a sh*t ton of weight."

We can definitely tell ... Keep it up!

Every day is Valentine's Day for these two!

Kat Von D and fiance Deadmau5 enjoyed a leisurely lunch at Urth Cafe in L.A. yesterday, and they seem more in love than ever!

The engaged pair linked arms and embraced on their way out of the restaurant, and we love how the edgy tattoo artist rocked her red rabbit fur purse in preparation for the romantic holiday.

We wonder what the brunette beauty got her man for V-Day?

"So nervous just now, giving Joel this valentines day present. Seriously so nervous..." she tweeted just moments ago.

In case you were wondering, Joel is the Canadian DJ's real name. Knowing how wacky these lovebirds can be, we can only imagine what her gift is!

The OWN network has released a 30-second clip from the upcoming Beyonce interview on Oprah's Next Chapter.

During the sit-down chat, Lady O asks Beyonce about everything ... from Bey's HBO documentry, her miscarriage, firing her dad as manager and the birth of Blue Ivy.

The 31-year-old entertainer is also asked whether she and hubby Jay-Z will have more kids.

Beyonce's new documentary Life Is But A Dream premieres Saturday on HBO. We'll be watching!

She's got that glow!

On Thursday Jessica Simpson and fiance Eric Johnson lunched at the Ivy at the Shore in Santa Monica, and the pregnant singer/actress got all dolled up for their Valentine's Day date in a baby pink blazer and black leggings. She's definitely not pulling a Kim K. and hiding that baby bump either!

Back in November the news broke that Jess and Eric were expecting their second child together, and she's reportedly due in July. Jessica gave birth to their first child, daughter Maxwell last May.

Jessica's former assistant/BFF CaCee Cobb and her husband Donald Faison are expecting their first child together, and Donald recently told People, “They hang out all the time anyway, but now they hang out and talk baby stuff, look at baby stuff online, and go shopping for baby stuff together." Fun!

Wonder if Jess and Eric are expecting a boy or another girl?

She has no shortage of admirers!

Kim Kardashian headed to her daily workout this morning, and on the way into the gym a fan surprised her with a bouquet of red roses for Valentine's Day!

We wonder what Kanye West has planned for his lady love on this romantic holiday?

The lovebirds have taken lavish vacations everywhere from Paris to Brazil recently, so maybe they are spending this occasion doing something more low key? Then again, this is Kimye we're talking about!

Just the other day, we spotted the reality star and her rapper beau exiting the doctor's office, and rumor has it the expectant parents found out the sex of their unborn child during the visit.

We have a hunch it's a girl!

They're back at it!

Vince Vaughn and Owen Wilson are back on the big screen together for the first time since Wedding Crashers, and we have a feeling they have another blockbuster on their hands!

The trailer for the upcoming film The Internship has just been released, and the movie centers around two men who lose their jobs and decide to work for Google as interns, where they find themselves competing against recently graduated nerds.

The comedy also features cameos by Will Farrell, John Goodman, Rose Byrne and Josh Gad. Shawn Levy will direct.

20th Century Fox originally wrote the script for Vaughn, who then pitched the film to Google. Although Google is not involved in the funding, they are working with the studio to promote the movie. They even allowed production to film scenes at their famous headquarters in Mountain View, California.

"It was the Wizard of Oz or the Chocolate Factory. Such a different place to work at that what is considered a traditional work environment, with the nap pods and the access to food, and of course the intramural sports on campus and massages and all that kind of stuff," Vaughn explained about immersing himself in the Internet giant's corporate culture.

Any movie with Vince and Owen is bound to be a knee-slapper!

Paris Hilton kept it simple and elegant in a skintight black dress while arriving for Topshop's grand opening party.

We're lovin' that black fur shrug and quilted Chanel purse. Thanks for the smile, P!

See which other fashionistas hit the LA party in our gallery below.

They're still battling it out!

Chris Brown and Drake are now suing each other over their June brawl at W.i.P. nightclub in New York City.

Romain Julien, a French model, filed a lawsuit against Brown and Drake after he reportedly suffered injuries during the fight, and now both of the singers have filed their own legal docs, trying to pin the blame on one another.

You see, if one of them is determined to be responsible for the fight, then they'll have to pay damages if Julien wins in court.
