There’s a new bromance blooming in Hollywood — and it’s between Zac Efron and Lance Bass!

Sources tell Star Magazine the gay former boy bander and the metrosexual heartbreaker have grown very close in recent months and have taken up daily gabfests by phone.

According to the Star insider: “They’ve grown very close. They talk a few times a week at least.”

Zac even bought a special birthday gift for his new bro.

“He got him a rocket pendant on a chain, since Lance loves space and wanted to travel to the moon.”
