The Twilight star kept a low profile (per usual, really) for the special occasion as they were seen partying at Soho’s The Box.

In a couple of Snapchat posts, the duo cozied up as Twigs blew out her birthday candles:
Glad to see these two lovebirds going strong! Hopefully we will get some wedding deets soon!!
