Chris Stark, the quirky BBC Radio host who called Mila Kunis "hot" during their interview last year, had an interesting run-in with another A-lister - Jennifer Aniston.

The reporter had no idea that his boss, Scott Mills, told Aniston to play the role of "worst interviewee ever" while he asked her questions about her new movie Horrible Bosses 2.

Things were going pretty smoothly until Stark told Aniston, "Because your character Julia is so forward, I'm interested to know how you would make the first move if you wanted to with a guy."

Aniston, who seemed very uncomfortable, told Stark, "First of all, I don't think that's an extremely appropriate question. I'm also committed to someone, I don't hit on people."

Stark attempted to explain the reason for his question but told her she didn't have to answer and even apologized.

Things got even more uncomfortable when he asked Justin Theroux's fiancee if she would ever write erotic fiction like "Fifty Shades of Grey."

Eventually, Mills saved Stark from his embarrassment as he entered the room and informed him about the prank. Stark seemed relieved.

"I'm so sorry," Aniston told him. "This makes me feel terrible."
