Old mates Kelly Osbourne and Alexa Chung caught up on Alexa's MTV show this week. The pair discussed everything from Kelly's ever-changing hairstyles to her new autobiography/advice book, Fierce (available September). Never one to mince words, Kelly stunned a studio audience member when they asked her what to do with a guy they are hooking up with who already has a girlfriend - funny stuff.

The girls were looking stylish as always with Alexa dressed in a cute spotted vintage dress and black Mary-Janes by Luella. Kelly personified "fierce" in a all-black ensemble consisting of sharp-shouldered Balmain jacket, black top and jeans. Note the yellow-painted nails too! Check out parts one and two of their interview after the jump...
