Good friends Miley Cyrus

ordering sushi at Koi Los Angeles with pals. The affectionate twosome "had a great time over dinner and were polite and friendly to everyone around them," a source tells us. When it was time to go, they "left with their arms wrapped around each other."
Despite attempting an incognito look – with a baseball hat covering his eyes – Leonardo DiCaprio
couldn't hide his affection for girlfriend Bar Refaeli
while hanging out at new L.A. lounge My House. The two held hands and hugged for a while – as if nobody was around, an onlooker tells us. Taking a bolder tact, Paris Hilton
and baseball player beau Barry Zito
amped up their PDA at the night spot. After getting down to her song "Stars Are Blind" (on top of a table), Hilton gave her beau a private lap dance then broke into a smooching session while their friends – including Hilton's sister Nicky
and boyfriend David Katzenberg
– looked on.
and wife Demi Moore
, dining at West Hollywood's Chateau Marmont with an unlikely group of celebrity friends, including Kate Hudson
and Penélope Cruz
. Despite the bevy of ladies at the table, Kutcher stayed focused on his wife. The actor did venture outside to the patio for a smoke break with Cruz, who brought her dog to dinner. Hudson, meanwhile, was the most low-key of the bunch, sitting on a couch at the table and just chatting with everyone.
Also at the Chateau that night: Kate Bosworth
and James Rousseau
. While Kutcher and his group ate in the hotel's lobby, Bosworth and her beau hung outside, sharing a kiss on the patio while hanging out with their friends. The pair also chatted with Penélope Cruz for a minute.
, buying matching running shoes at New York's JackRabbit Sports with husband Paul Bettany

Also in the Big Apple, Alyssa Milano
grabbed a comfy booth at Koi New York with fiancé David Bugliari.
The couple were laughing over their crispy rice and baked crab hand rolls. Dining with three friends, "they were all really casual and were all smiles," a source says.
