On-again couple Miley Cyrus
and Liam Hemsworth
cuddled up on the couch in the Dragon Room, a private dining room at Katsuya
in Brentwood, Calif. The two were catching up and "looked so in love," an onlooker says, of their dinner date. According to the onlooker, Cyrus also enjoyed milk and cookies in between whispering into her Aussie beau's ear.
and hubby Josh Duhamel
were sharing a bottle of wine and toasting with two male friends during a evening out at West Hollywood's Chateau Marmont.
The foursome sat on the patio, and seemed to enjoy each other's company, foregoing dinner and dessert for their drinks. At the end of the night, Fergie pulled out a phone and shared several pictures with the group, while Duhamel looked at his wife adoringly. Later, the two set out – holding hands.
