Miley Cyrus was spotted lounging on the beach with friends in Brazil this afternoon. She was also joined by her mom, Tish, who showed off her huge back tattoo in a hot-pink two-piece. Miley fit the bikini time in between her busy Gypsy Heart Tour, which has her traveling around the globe to show off her latest album, Can't Be Tamed. Miley's already been to Chile, Argentina, and other South American stops, and she's set to take the stage in Rio de Janeiro and Sao Paulo this week. She'll be on the go until July when she wraps things up in Australia, but it looks like she has plenty of company to keep her entertained during her travels. Tish has proven to be one of those fun companions since she tweeted embarrassing pictures of Miley sleeping during their most recent flight.
