Miley Cyrus can't stop (and she won't stop!) growing out her armpit hair! Somewhere Patrick Schwarzenegger is cringing...

On Friday the 22-year-old superstar posted a few shots on Instagram, and in one she appears to be smoking pot, and in the other she models a sexy one-piece swimsuit while also showing off her bushy pit hair. "PITZ & TITZ," she captioned the shot on the right. Well put, Miley!

While the singer/actress has been heating things up with girlfriend Stella Maxwell, is there bad blood with fellow starlet Taylor Swift? In a word, maybe! The other day Miley re-posted a meme featuring Taylor Swift and Justin Bieber with the caption, “If you face swap Justin Bieber and Taylor Swift, they look like a cute lesbian couple.” Miley tagged herself and Maxwell in the shot, and get this -- Taylor then commented on it! "Sending you love," she wrote.

But what does this really mean?! "Taylor thinks the way that Miley carries herself is a little embarrassing and doesn’t want to be involved with any of the wild stuff she does," a source tells Hollywood Life. “[She] would like it if Miley stopped making photos of her and referencing her." Can't say we blame her, but the pic was pretty hilarious...
