Britney Spears has revealed that she takes inspiration from her ex-boyfriend Justin Timberlake.

The two pop stars dated for some time in the early 2000s before splitting.

However, it seems that the '20/20 Experience' man is still a source of influence and inspiration for the former X Factor USA judge..

She told USA Today: "Bruno Mars is so different and fresh, and Justin Timberlake is, too. It's inspiring for me, and it makes people eager to listen to music, which helps everyone."

Spears added: "I look up to Beyoncé, what she did with her album was genius, really brilliant."

The pop princess meanwhile is in the opening stages of her two-year Las Vegas residency at Planet Hollywood.

The show, which delves into the singer's back catalogue, kicked off on December 27.
