What a pair!

The ORIGINAL rebel, Madonna, posed with her younger counterpart, Miley Cyrus, at the 2013 Billboard Music Awards Sunday night at the MGM Grand Garden Arena in Las Vegas.

Madonna took home three prizes -- for Top Dance Album, Top Touring Artist and Top Dance Hall Artist. Wow!

Miley, meanwhile, made a splash in her super-sexy crocheted Balmain jumpsuit with black and while harlequin and lots of peek-a-boo pieces. And during the pre-show, the 20-year-old announced her new single "We Can't Stop" will debut June 3 on Ryan Seacrest's radio show. Can't wait!
