Christina Grimmie is the latest artist to offer a tribute to Whitney Houston. The teen singer, one of PopCrush's Artists to Watch for 2012, performs 'I Will Always Love You' in a new video in remembrance of the late pop and R&B diva.

Grimmie opens the clip with an explanation for why she's not playing piano, as she does in many of her other videos: "This song is just so big, and honestly, I can't make it through without tearing up or crying or falling short. So there was no way I could do it justice without singing to a karaoke, which is what I did for this one. But I honestly feel like I have it my all and I gave it my best in honor of Whitney. I really love her so much."

The clip is audio only — Grimmie isn't shown after her introductory remarks. She tackles the a cappella opening with ease, sending early notice that her voice is perfect for the song. Singing along with the pre-recorded music, Grimmie changes the vocals just enough to show off her own talents without deviating too much from Houston's delivery on the 1992 blockbuster hit song. Now this is a killer cover!

Selena Gomez even tweeted a link to Grimmie's performance, saying, "Amazing job." Grimmie's recording follows Aretha Franklin's own tributes to Houston, Elle Varner and the Roots' performance of 'Saving All My Love for You,' Charice's 'The Bodyguard' medley, and Robin Thicke's cover of 'Exhale (Shoop Shoop).'
