Talk about putting on a show!

Taylor Swift performed her current hit "I Knew You Were Trouble" at Wednesday's Brit Awards, which wouldn't really be a big deal... except for the fact that she did it in a sexy, black, lingerie-inspired jumpsuit with her ex-boyfriend Harry Styles looking on in the audience.

The country-pop singer started her performance in a big angelic white gown, only to strip down to the sexier look that suited the song much better.

Although precautions were reportedly taken at the awards show to keep Harry and Taylor apart, the One Direction band member seems to have no hard feelings. "Great!" he told Us Weekly regarding his ex's performance. "She always puts on a good show."

Luckily, Taylor didn't have to worry about Harry showing up to the show with a new girlfriend -- he took his mom as his +1! Awwwww.

Do you think Taylor and Harry could ever get back together?
