The actor was spotted yesterday getting all lovey dovey with his new girlfriend of at least three months, personal trainer Lia Smith.
Regardless of his Hangover persona, Justin seems like quite the chivalrous gentleman.
That Lia is one lucky lady, but will she be lucky enough to be Justin's date to the Hangover III premiere in a couple of months??
We'll just have to wait and see!
