• Nick Lachey and Vanessa Minnillo, hanging out poolside in a cabana at San Diego's Ivy Hotel. Apart from her beau, Minnillo had another friend to keep her company during the mini-vacation: her dog, Wookie, who also got the royal treatment on a pet bed set up by hotel staff. While the duo lived it up – hitting Damon Gordon's Quarter Kitchen lounge, among other spots – they were also there for a good cause: the Jimmie Johnson Foundation charity dinner and golf tournament.

• Melanie Brown and hubby Stephen Belafonte, hanging out at West Hollywood hotspot Hyde together. Sitting side by side, the pair were chatty – with each other and another couple. At one point, Belafonte headed outside (sans Brown) for a smoke break, but he soon returned and the pair hopped right back into their conversation.
