Last night Rihanna jetted from New York City to Los Angeles, and after spending some quality time with her family over the weekend, the R&B songbird is back in town to handle her business.

Rihanna may have kept her travel attire on the comfy and casual side, but her face was 100% camera ready ... c'mon, would we expect anything less from the 24-year-old starlet?!

Kourtney Kardashian, Scott Disick and little Mason went to Joan's on 3rd over the weekend, and later we spotted the trio heading to birthday party in Hollywood.

While the pregnant reality TV star wasn't able to attend brother Rob's 25th birthday bash in Las Vegas on Friday (she was doing a live event to promote the K-DASH by Kardashian on QVC), she sent him plenty of sweet birthday wishes. Hopefully he'll understand -- and hopefully he won't hold it against her when she has a baby shower later this year!




X17online has the first pix of Josh Hartnett and Amanda Seyfried together -- and together they are! The pair left Amanda's house and went grocery shopping together Saturday afternoon ... looks like these two are shacking up!

Seyfried, 26, and Hartnett, 33, are said to have been dating since January, but they've done a good job keeping their relationship under wraps.

Amanda dated Ryan Phillippe and had a long relationship with British actor Dominic Cooper, while Josh dated Kirsten Dunst and Sienna Miller.

Jessica Simpson celebrated the impending birth of her baby girl with family and friends by her side, Sunday. Simpson, 31, and boyfriend Eric Johnson were joined by Jess' sis Ashlee and her ex-husband, Pete Wentz and his new girlfriend Megan (awkward!). Celeb guests included Ellen Pompeo and Jessica Alba -- Simpson's Fashion Star co-star Nicole Richie was noticeably absent ...

The party was colored in pink and yellow and the entrance to the shower shindig was decorated with hay bales -- appropriate for the Texas native. Party planners hauled bags of gifts inside the Culver City venue. No doubt this soon-to-be-mom made out with some serious booty!

At least Christina's rollers were green for St. Patty's Day! The actress hit the set of her NBC comedy Up All Night with her hairdo still underway ...

But hey, she's a working mom! The actress recently told Access Hollywood that her real life parallels her on-camera life, having her year-old daughter Sadie who keeps Applegate and her partner Martyn LeNoble busy.

The two have yet to tie the knot, but Christina says having a baby together is stronger than any piece of paper: "For me [getting married] doesn't add to the fact that we love each other and that we're going to be together and that we have this incredible human that bonds us for life - literally for life. So I think we're good."

Whew, that was close!

Nearly 9 months pregnant and about to pop, Jessica Simpson narrowly avoided a major catastrophe when a palm tree branch came just inches from falling on her during a walk with artist pal Tom Everhart and fiance Eric Johnson in Venice, on Saturday afternoon.

Luckily Miss Simpson, who donned green boots and a matching Hermes Birkin for the St. Patrick's Day outing, was able to walk away from the incident with a smile on her face.

Flaunting her Skinny Girl frame in a sexy pair of black skinny jeans and stiletto boots, Bethenny Frankel enjoyed a brisk walk though NYC's posh Soho neighborhood with darling baby Bryn, on Saturday.

But while the mommy-daughter duo seemed to be enjoying the afternoon outing, hubby Jason Hoppy looked less than pleased. Earlier this week, The Real Housewives of New York star told Anderson Cooper that her marriage was more difficult than she thought it would be.

"We didn't date for that long and we were pregnant and so many different things happened at the same exact time including having a baby and my business," Frankel confessed on CNN. "We were also older, when you get married older you're set in your ways and that's when the acceptance really has to come into play."

Should we be expecting a Bethenny Getting Divorced series in the very near future?

When it comes to casual yet sophisticated style, Kellan Lutz always hits it right on the head!

The Twilight hottie, who was happy to greet his fans of all ages, showed off Dylan George's ready-to-wear menswear collection, Abbot + Main ... in which Kellan designed with DG founder Danny Guez.

We're lovin' those jeans!
