Was it bring your fiance to work day?
In fact, it seems that Liam can't even get through a work day without seeing his boo. Yes, we know we're not cool enough to use the word boo.
Perhaps due to a serious case of 'missing-that-hot-face-itis' Miley rocked up to spend some time with her fiance as he filmed scenes for his latest film, Paranoia, in Philadelphia - which sees a boss blackmail his young employee to spy on a rival company.
The pair quickly scooted-off to Liam's trailer for some on-on-one time, which we're sure involved a very intense game of scrabble, rather than anything else. *ahem*
Sporting a black low-backed playsuit, converse and rather fetching top knot, it's no wonder Liam wants Miley around. She's looking F to the INE.
On a scale of one to ten - how cute are this couple?
