Kelly Clarkson Photobomb at Grammys [PHOTO]: Songstress' Hilarious Ellen DeGeneres, Portia de Rossi Photobomb Highlight of the Night? [POLL]

Pop star Kelly Clarkson was just one of several stunningly talented celebs who stole the show Sunday evening at the 55th annual Grammy Awards in L.A. Not only did the 30-year-old "Stronger" songstress perform a beautiful tribute to female pop legends Patti Page and Carole King, but she snagged the Grammy Award for "Best Pop Vocal Album." Oh, and did we mention that Clarkson even managed to pull off one of the best photobombs of the night? That's right - Clarkson's hilarious "Hey, I'm with them" photobomb of Ellen DeGeneres and wife Portia de Rossi has since gone viral on the web. Some fans consider Clarkson's "unintentional" (but totally intentional) photobomb of the famous couple a major highlight of the evening.

Clarkson kicked-off her Grammy appearance with a rather amusing acceptance speech for "Best Pop Vocal Album." The "Miss Independent" songstress' nervous jabber had most of the crowd chuckling:

"I got stuck on Miranda Lambert. There's a story and a song. For later, after alcohol," Clarkson joked, referring to her dress getting caught on Lambert's sparkly attire on her way up to the stage. "I'm just kidding, children. I get nervous speaking in front of people."

She went on to recognize Fun., her "sexy" fiancé Brandon Blackstock, and fellow Grammy Award winner Miguel. Check it out:

Clarkson also performed an amazing tribute to the late pop icons, Patti Page and Carole King, before presenting the award for "Best Country Album" to the Zac Brown Band for "Uncaged":

And to wrap up a phenomenal night, Clarkson posed for a pic with popular television personality Ellen DeGeneres and her wife Portia de Rossi... without them exactly knowing it:

@keepinitblog: "So, Bill Clinton photobombed @kelly_clarkson at the Inauguration...now it's her turn to photoblomb @TheEllenShow!"

Oh, and that last tweet is referring to this:

So what do Mstarz readers think - besides Clarkson's awesome 2013 Grammys experience, was her audience celeb photobomb one of the highlights of the evening?
