Washington, March 23 : Actress Cameroon Diaz and ex-beau Justin Timberlake have sparked off rumours of their reunion after they were spotted enjoying each other's company in Los Angeles.

The pair, who broke up in January after nearly four years together, was seen spending quality time with each other at the Whisky Bar in the Sunset Marquis Hotel in West Hollywood on March 9, reports Contactmusic.

According to In Touch magazine, the 'Charlie's Angels' star and the 'Sexy Back' singer were again spotted surfing together during the same weekend at a Malibu beach.

Diaz was earlier in the news because of her alleged link up with Oscar nominee Djimon Hounsou, with whom the 34-year old actress was seen at a post valentine party.

Onlookers said that Diaz seemed to be enjoying the actor's company and claimed that the two were totally vibing each other.

However, Diaz's rep has said that the two are just friends and that the actor joined Diaz and her gang for a drink.
