Wilmer Valderrama and Minka Kelly are apparently having a good laugh about their romance rumors. After photos of them walking arm-in-arm in Sydney, Australia added more fuel to speculations that they are becoming more than friends, the two TV stars have a Twitter banter to shoot them down.

First to bring up the topic was 32-year-old Valderrama as he tweeted, "Yo @minkakelly were you romantically gazing into my eyes, while romantically having a stroll? Ha!" In her response, 31-year-old Kelly wrote back, "@WillyVille HA! Yea just before gazing into the other 12 peoples eyes we were with! Jeez! #theyregonnabepissedtheydidntmakethephotos."

Valderrama and Kelly were first linked romantically together in March. They were, at the time, spotted together in a private booth at the Greystone Manor in Los Angeles. An onlooker said that the pair were "all over each other" throughout the night. The witness additionally noted, "They were very flirty and dancing close. They even left with each other."

In a recent interview with Ryan Seacrest's KIIS FM radio show, Valderrama insisted that he and Kelly "have been friends for a long time." However, on Tuesday, April 3, the two were spotted taking a cozy walk along the water at Balmoral, Sydney. This time around, the "That '70s Show" alum was photographed having his arm draped around the "Charlie's Angels" actress.
