Lady Gaga Loves Christina Aguilera’s New Single ‘Your Body’

We've learned two things about Lady Gaga courtesy of her tweet about buying and loving the new Christina Aguilera single 'Your Body.' One, she still buys (as opposed to illegally downloads) music. And two, she is a class act who takes the high road and shows love to her fellow divas, even when they diss (or have dissed) her.

Fresh off a new diss from Madonna, who refuses to grow up and let it go by declaring imitation to be flattery, Gaga tweeted that she is happy the "old" Xtina is back on this song, since she had diverted from the path on 2010's flop 'Bionic.' While on the promotional trail for that album, Xtina actually dissed Gaga more than once, claiming to not even know who she was and questioning her gender.

"This person [Lady Gaga] was just brought to my attention not too long ago. I'm not quite sure who this person is, to be honest. I don’t know if it is a man or a woman. I just wasn’t sure," she told the L.A. Times. Ouch. How rude!

She also sniped, "Oh the newcomer? I think she is really fun to look at" to Out when the subject of Gaga came up, since her star was on the rise while Christina's was stagnating.

What is it with pop veterans hating on Gaga so much? Are they just jealous? We're going to venture a guess that that's the deal, since she's so good at what she does. Even though Christina was nasty to her in the media, she still sent her love and congrats. That's called taking the high road and being an example for little monsters to emulate.

Below is Gaga's tweet. Sounds sincere to us. She also tweeted that she was obsessed with No Doubt's comeback single 'Settle Down' recently, too.

@therealxtina just bought your new single. Seems the old Christina i loved has returned! Congratulations!! :)
