Guess they weren't in the mode to play dress-up!

But the affectionate couple, who were spotted kissing during the party, weren't alone for their outing. Pattinson's longtime pal Katy Perry arrived at the shindig with the twosome with a predictably more elaborate ensemble. The "Last Friday Night" singer, 28, dressed as Jane, the goth best friend of Daria in the beloved MTV animated show. (One night earlier, the chart-topper had a reunion of her own: She attended the L.A. Lakers game -- with ex-husband Russell Brown spotted across the stadium at Staples Center.)
