Rihanna 'flirts' with Ashton Kutcher amid Drake dating rumors, 'jealous' girlfriend Mila Kunis 'flips out' over 'Two and a Half Men' bonding?

Rumors suggest that Ashton Kutcher and Rihanna might start working together on the set of "Two and a Half Men." And apparently Kutcher's "That 70s Show" girlfriend Mila Kunis isn't too happy about it.

A recent shady report in the National Enquirer begins with, “A miffed Mila Kunis is flipping out over boyfriend Ashton Kutcher’s friendship with R&B sex bomb Rihanna — and she read him the riot act after discovering they were exchanging phone calls."

Hmm... do Mstars fans view Kunis as the jealous type? Come on now, she was once named "Sexiest Woman Alive!"

The infamous gossip webloid explains that Kutcher recently approached RiRi about guest-starring on an upcoming episode of the hit comedy series "Two and a Half Men." But Kunis is jealous about their back-and-forth business convos, because she knows that the "Diamonds" songstress "nearly irresistible to men."

An alleged source reveals that the "Black Swan" beauty "angrily ordered Ashton to cut his ties to Rihanna - or else!"

Once Kunis discovered that Kutcher was chatting it up with RiRi, "Ashton apologized and promised never to talk to Rihanna again without first getting Mila's permission."

Sounds a little crazy. The relationship between Kunis and Kutcher appears to be doing just fine. Hollywood's all about acting the part - that doesn't mean friendly co-star chit-chat directly leads to infamous cheating scandals. Remember when the same thing happened with Kunis and Channing Tatum?

Anyway, a source close to the situation tells Gossip Cop says there's "no truth" to these latest allegations. Kunis is not jealous of Rihanna talking with her beau.
