Ever since MEGAN FOX announced at last year’s GQ Awards that she was “obsessed” with ZAC EFRON, sources have been whispering that the super-sexy actress is going all out to steal the HSM hottie off his girlfriend, VANESSA HUDGENS.

Making her move on Zac at the Globes after-party, a source revealed, “There were times when they seemed lost in conversation together, while Vanessa stood by like a sulking girl.”

But 20-year-old Van isn’t taking the challenge lying down. Ahlan! reveals Ms Hudgens’ three-point plan for keeping Zac close… and Megan even closer!

Vanessa’s three-point ‘keep zac’ plan!

1. Be Megan’s Bestie
As a Tinseltown insider reveals, “Megan acts likes she’s best friends with Vanessa, but flirts with Zac every chance she gets,” Vanessa has decided to play along with the NBF charade.

Spotted at the Globes after-party holding Megan’s hand and sitting next to her all night, Van ensured the Transformers star was not alone with Zac for a second.

2. Cosy Up To A Hottie
As sources comment on the “chemistry” that is simmering under the surface between Zac and Megan, Vanessa’s been reminding her man of 20 months that she can attract a Hollywood hottie too!

Cosying up to upcoming star, Taylor Lautner – Twilight’s Jacob Black – at a recent Access Hollywood bash, sources say that the pair bonded over Van’s rumoured audition for the third Twilight movie, Eclipse. And Taylor’s made it very clear that he’s looking for a girlfriend, saying, “I look for someone honest, loyal and someone who can be a dork.”

3. Make Zac Jealous
Vanessa’s rumoured involvement in Eclipse left sources revealing that Zac felt insecure and jealous that she would be hanging out with Robert Pattinson on set, with pals revealing, “At least Zac can take comfort from the fact that at least she wouldn’t be kissing him!” And it seems as if Van’s careful playing up to the rumours has worked, with a friend of the Hairspray star, revealing, “There is a bit of jealousy there.”
