For the second week in a row, Britney Spears
headed to Sin City. One week after taking the stage at Rain Nightclub
, Spears returned to Las Vegas's Palms Casino Resort along with beau Jason Trawick
and her two boys. The four grabbed a casual dinner in the private dining room at Nove Italiano, where the kids enjoyed a mozzarella pizza, which was waiting for them as they arrived. Meanwhile, Spears drank a Sprite and ate halibut. According to a source, "Britney was very quiet … but her kids were very nice and looked great."
and Sean Penn
continued to revel in their new relationship
with a night out at West Hollywood's Chateau Marmont
. The dressed-down couple spent the early evening on the back patio, and "they seemed totally comfortable with each other and at ease," an onlooker says. When it was time to leave, the onlooker says: "They held hands and walked confidently through the hotel."
The rainy Paris weather didn't keep Ryan Phillippe
and girlfriend Amanda Seyfried
from exploring the city. Heading out with some friends, the couple headed out toward the Eiffel Tower, then stopped into the café Le Champ de Mars for lunch, followed by more sightseeing, including a stop by Napoleon's tomb at Les Invalides.

, hanging out in a luxury bungalow at Surrender Nightclub in Las Vegas. The two were really cozy during their night out, and hung out with an eclectic group, including Vin Diesel
and Crispin Glover.
and Courtney Mazza
never left each other's sides at the Tom Ridge Homeland Security Awards in N.Y.C. The couple handed out American flag pins and were laughing with a group and posing for pictures.
