Justin Timberlake and Jessica Biel bundled up in black coats and scarves to hit the town for Jessica's 27th birthday in NYC last night. The cozy couple kept things low-key, catching a performance of Will Ferrell's You're Welcome America on Broadway. It's been a busy week for Justin who also helped Jimmy Fallon kick off his late-night hosting duties, but a special birthday date night with his girlfriend is not something he could skip.
