A source claims that Chris Pine and Olivia Munn have not parted ways -- despite Monday's reports online of a breakup.

An insider close to the Star Trek actor and Iron Man 2 actress is disputing Monday's announcement of a split. "They are not broken up, " the insider insists to "They are just having fun and being casual."

Although Monday's report said the pair avoided one another at a Friday event, an insider observed them being affectionate that same night at the Buffalo Club CAA party in L.A.. "They remained inseparable during the night," the eyewitness tells "Constantly whispering, holding hands and sharing a cup of hot mint tea."

Pine and Munn, both 29, reportedly starting dating about five months ago.
