Miley Cyrus Goes Face-Deep in Amazon Ashley's Boobs, Motorboats Dancer's Cleavage—See the Pic!

Bangerz beauty follows up Katy Perry kiss with raunchier onstage move

Miley Cyrus isn't always baring her boobs--sometimes she's burying her face in someone else's!

The 21-year-old singer did just at her Bangerz show Friday in Illinois, getting up close and personal with Amazon Ashley's ample cleavage onstage.

Amazon Ashley looked rather enthused to have Ms. Cyrus face-deep in her chest, motorboating away in front of a packed crowd. Miley tweeted a picture of the intimate interaction, adding simply, "Love you @amazonashley67."

And the feeling is mutual. Amazon Ashley, who also dances at Beacher's Madhouse in L.A., tweeted a shot of Miley gearing up to smack her behind. "I love @MileyCyrus," she wrote, "having the #Timeofmylife."

It sure looks like it! Amazon Ashley isn't the only lady to get a little love from Miley mid-concert, though. Last month, the Queen of Twerk locked lips with Katy Perry during her Bangerz concert in L.A.

"I just kissed a girl and I really liked it a lot," Miley declared after their lip-lock.

But when Katy, 29, jokingly dissed their kiss on the Australian talk show Sunrise, Miley fired back on Twitter, taking a not-so-subtle dig John Mayer and his playboy reputation. "Girl if ur worried abt where tongues have been good thing ur ex boo is ur EX BOO," she wrote, "cause we ALL know where THAT [tongue] been."

Naturally, Katy tweeted back, promising to give Miley "the BIGGEST spanking" when she sees her next.

Miley's response? She tweeted at the "I Kissed a Girl" singer, writing, "Dontchyouuuu act like you didn't lurvvvvv it."

Atta girl.
