LMFAO star Redfoo is set to serve up his own line of tennis wear.

The "Sexy and I Know It" hitmaker has been quietly working on his own sporting collection and the singer, who is known for his wacky style, gave attendees at the U.S. Open Championships in New York a preview of his upcoming designs this week by dressing junior tennis player Ayaka Okuno in colorful attire from his new range.

Okuno modelled racy purple and black leopard-print shorts under a black tennis skirt in the Lacoste lounge, while Redfoo chatted to former doubles champion Murphy Jensen.

The musician, real name Stefan Gordy, hopes to launch the as-yet-untitled apparel collection later this year, according to the New York Post's Page Six column.
