Peter Facinelli goes on rumor patrol for Robert Pattinson, Lea Michele models in her underwear, and Carrie Underwood reveals her hockey player husband doesn't have any real teeth left. Watch today's all-new PopSugar Rush!

Sienna Miller joined her sister Savannah at last night's announcement of the 2010 British Fashion Awards nominees in London. Since purchasing a new home with Jude Law earlier this month, Sienna's been sticking close to home base, though they did have an epic Summer family vacation with his kids, which earned more than one spot in our best bikini and shirtless pictures of the season. Sienna chose a lovely shade of green for the gathering and accessorized with a bangle large enough to cover up the reported marriage blessing wristband she's been wearing.

Ashley Tisdale bared her belly and held onto her pompoms on the set of Hellcats in Vancouver yesterday. The actress plays college cheerleader Savannah in the upcoming CW series but is quick to point out her new character's distinctions from the one she played in High School Musical. Ashley's show may not be entirely groundbreaking, but the workouts are certainly keeping her bikini body in shape. She'll also be returning to her roots as Sharpay in the upcoming HSM spin-off, though this time she won't be joined by her real-life best friends and former costars Zac Efron and Vanessa Hudgens.

Rihanna wore a stomach-baring Alexander Wang sports bra as she touched down in Oahu and got straight to work on the movie Battleship yesterday. It will be the singer's big-screen debut, and she'll be in good company in the adaptation of the popular board game, working alongside sexy costars like Alexander Skarsgard and Taylor Kitch. The shoot comes at the tail end of a busy Summer for the singer, who got lots of attention for her role in Eminem's controversial Love the Way You Lie video, spent lots of time with her baseballer boyfriend Matt Kemp in LA, and jet setted around the globe, performing everywhere from Toronto to Spain in recent months. Now we'll hopefully get a glimpse of her alongside her hot castmates in Hawaii!
