The 28-year-old actress has denied that she is romantically involved with Kutcher and said that the rumours were "absurd", reported People magazine.
"It is absurd! A friend is a friend," Kunis said.
A source said that the two just spent a cozy weekend together in Carpinteria, California are enjoying spending time together, but not ready for a serious relationship.
"They're both single, having fun. There's nothing serious going on, just friends having fun," said a source.
The pair have been spotted together numerous times in the last few weeks, and were even snapped furniture shopping before retiring back to Kutcher's new Los Angeles pad. PTI CORR JCH
