Saucy teen tart MILEY CYRUS cut off ALL her hair – and now she’s gone on a gay smooch fest!

The former “Hannah Montana” star, who recently became engaged to longtime boyfriend Liam Hemsworth of “Hunger Games” fame, is sowing her wild oats before the wedding – by smooching other women.

“Miley decided to live a little before she ties the knot,” an insider told The ENQUIRER. “She wants to have some fun and laughs before she gets bogged down with wedding plans.”

Miley, 19, was spotted sharing an intimate kiss with an unidentified woman at New York’s trendy club The Darby on Aug. 23 while her 22-year-old fiance was hard at work shooting his new film, “Paranoia,” in Philadelphia.

“Miley has always been outspoken over her support of gay rights,” the source continued. “She even sports a small equal sign tattoo on her ring finger to signify her belief that all love is equal.

“So it’s certainly not surprising that she’s experimenting with girls before she walks down the aisle.”

This isn’t the first time the onetime Disney darling has locked lips with another young lovely. In 2010, she puckered up with a cutie onstage during a performance of “Can’t Be Tamed” at London’s legendary G-A-Y nightclub.

At the time, the “Party in the USA” singer defended the kiss by claiming “nothing happened” and there are “more important things in the world” than two girls kissing onstage.

But Miley’s behavior was enough for self-professed bisexual actress Evan Rachel Wood to take notice!

After seeing Miley’s new do, Wood tweeted: “I called it! Miley Cyrus is leaning toward gay!”

Meanwhile, Miley’s career remains red-hot as she recently inked a deal to appear in a two-part episode of the hit sitcom “Two and a Half Men.”

“Miley’s having the time of her life right now,” added the source. “She knows she’ll have to settle down once she and Liam get hitched, but for now she seems to be living by the motto, ‘Girls just want to have fun!’”
