Now that Britney Spears nude is almost a common sight - right, Matt Encinias? - the troubled singer has decided to change up her appearance a bit.

Take a close enough look below and you can see the ex-wife of Kevin Federline with green eyes. So at least she's doing something for the environment!

The normally brown-eyed pop star was caught leaving the set of a video shoot in Santa Monica wearing a lace see-through top and black hotpants... in addition to emerald green contacts, according to to celebrity gossip site and photo agency X17-Online.

Britney Spears looks as normal as ever after her latest attempt to film a music video.

As she exited the set, Britney was spotted with a large diamond on her ring finger and had her so-called cousin Alli Sims in the car as she headed to a drive-in burger restaurant.

Sims has recently tried to launch her own music career, one that sees more promising already than that of Brit.

These days, of course, the future of Brooke Hogan in pop music looks brighter than Spears'.
