It looks like Selena Gomez could be giving ex-boyfriend Justin Bieber a taste of his own medicine…

The 20-year-old half-Mexican-American  singer/actress covered Justin Timberlake’s “Cry Me a River” at her third annual UNICEF charity concert in New York over the weekend, only weeks after breaking up with the Biebs. Gomez’s ex performed the exact same song in November following the couple’s first break-up.

“I’ve been through a lot the past few months. It’s been weird and sad and cool,” Gomez told the crowd. She then confessed, “This song definitely speaks to me,” right before performing a stripped-down version of Timberlake’s smash break-up track.

Gomez followed it up with another break-up tune, her bestie Taylor Swift’s “I Knew You Were Trouble.

“It’s by my best friend in the entire world and if anybody has felt anything painful to their heart, they know who this girl is. Sing along if you know it,” said Gomez.

In addition, Gomez offered event attendees her rendition of Britney Spears‘ “Baby One More Time“, possily alluding to her upcoming film with Vanessa Hudgens and James Franco, Spring Breakers, which is reportedly  filled-with Spears covers.
