Caught in the Act!

• Orlando Bloom, getting into the beat –thanks to his iPod – while messing around with his pooch Sidi at a Los Angeles-area park.

• Dancing With the Stars' Julianne and Derek Hough, taking in the courtside action at a Utah Jazz game in Salt Lake City. Not all the action happened on the court: In their home state for the holidays, the siblings laughed hysterically as the Jazz's mascot – a bear – got touchy with Julianne, draping his arm around her neck and, at one point, sitting on her lap.

• Justin Long, also home for the holidays, returning to his favorite local spot, the Southport Brewing Company, in Connecticut – this time sans girlfriend Drew Barrymore. During his recent visit, the actor brought along his lookalike brother, Christian, for some beers with buddies.

• Mandy Moore, swinging by the Apple store at The Grove in Los Angeles for a bit of shopping. Her purchase? Some iPod speakers. The singer also hit up the Barneys New York's Co-Op before heading toward her car.

• Kate Bosworth, savoring the seasonally-appropriate Eggnog Tiramisu with a pal at West Hollywood eatery Il Sole. Also enjoying the dessert just across the restaurant: Entourage star Jeremy Piven – who shared the treat with a lady friend.
