{blackbabes} Caught in the Act!

• With a June wedding on the horizon, Hugh Hefner and fiancée Crystal Harris huddled close all night at the Playboy Golf Lingerie and Pajama Party at the Playboy Mansion in L.A. The two "looked smitten," according to a source at the soiree, where the soon-to-be 85-year-old also received a life-sized birthday card from Playboy Golf CEO Ajay Pathak and a bevy of Playmates.

• Justin Bieber, stopping into Benihana in Encino, Calif., with his dad Jeremy for a late dinner just after 10 p.m. The pop star always orders the same thing at the restaurant, according to a source: a California roll and a non-alcoholic strawberry-flavored drink.

• Jennifer Hudson celebrated the release of her new album I Remember Me with a bash at Tenjune in N.Y.C. The singer arrived with a large entourage, including music mogul Clive Davis and plenty of friends and family. A source says Hudson looked "elegant and happy in a fitted sequin dress" as revelers sipped Ciroc vodka drinks and danced all night.

• At the Fader Fort by Fiat in Austin, Texas, Diddy scouted out new bands as part of the South by Southwest festival – and the music mogul had good company: his protégé Cassie, who took in the shows from the side of the stage with him. Later that night, rapper Kanye West was hanging out with pal Mos Def, while Parks and Recreation's Aziz Ansari rocked out to an early evening show by newcomers Odd Future.
