On the day it was confirmed that Rihanna
was subpoenaed to testify
against Chris Brown
at a June 22 hearing into his assault case, the "Umbrella" singer hit the town with friends – including Aubrey "Drake" Graham, the Canadian rapper to whom she's recently been linked.
The pair were spotted smooching
on May 18 at Lucky Strike Lanes & Lounge in Manhattan. On Wednesday night, Rihanna and Graham laughed and chatted at a bash for the Black Eyed Peas' Target deluxe version of their album, The E.N.D.
, held at the N.Y.C. nightspot The Griffin.
Rihanna – looking stunning in a light grey sweater dress and large hoop earrings – arrived at The Griffin shortly after 11:30 p.m. and stayed nearly two hours. Drake left a bit earlier – only to wait outside the club's front doors. Both he and Rihanna drove off at the same time, in separate vehicles.
While in the club, a happy-looking Rihanna, 21, appeared to be enjoying herself, holding court in a banquette to the left of the stage, where will.i.am DJ-ed the party – and gave an affectionate shout-out to Rihanna when she entered the club. Besides mingling with fellow guest Wilmer Valderrama, Rihanna also walked hand-in-hand up to the DJ booth with Fergie
As for entertainment, Fergie and the Peas performed "Meet Me Halfway," "Now Generation" and "Electric City" from their new album, while Will.i.am played a range of songs, including "Pump Up The Jam," "American Boy" and "Show Me Love." For her part, Rihanna bobbed her head to the music, danced a little and lip-synced "American Boy."
