Man-eater Megan Fox is on the prowl for some High School Musical meat, according to the latest report.

Megan was reportedly seen making flirtatious advances towards Zac Efron at the Golden Globes after party - much to the despair of Zac's long time girlfriend and co-star Vanessa Hudgens.

A source tells the National Enquirer, "It was easy to see the connection between Megan and Zac.

"There were times when they seemed lost in conversation together, while Vanessa stood by like a sulking girl.

"Vanessa is lovely. But Megan is considered one of the hottest women on the planet - and when you get right down to it, she makes Vanessa look like a teen starlet by comparison. It couldn't have been easy for her to watch Zac lap up all of Megan's advances.

"It was clear Zac and Megan have lots of chemistry."

An insider added, "Megan acts likes she's best friends with Vanessa, but she flirts with Zac every chance she gets!

"Zac's been faithful - but it can't be easy for him!"

Somewhow we're not sure Zac is Megan's type....
