What the hell happened to the good old Gaga/Xtina feud?

Remember that amusing time when Lady Gaga and Christina Aguilera were (supposedly) feuding with each other? For those of you who don't, welcome to the history class, I'm gonna take you a few years back.

It all started in 2010 when Xtina (now also known as Xtincta) released her album Bionic, which basically flopped like hell. The first single off Bionic, Not Myself Tonight, performed poorly and Xtina was heavily criticized and accused of copying Gaga.

Xtina fans, and even Perez Hilton (who was in a love/hate relationship with Gaga), accused Gaga of sabotaging Bionic and Xtina's career.

Of course, Xtina was really unable to do anything at that point. Still, she did not sit quietly. When asked about Gaga in an interview, she condescendingly called her a 'newcomer' and said:

"You know, that's funny that you mention that. 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."

Ouch. Sounds like someone was pressed...

 Yep, those were the fun times. Now fast forward a few years ahead, we come to the present day where this happens:

Last night, Xtina and Gaga performed Gaga's latest single Do What You Want (not featuring R. Kelly) on The Voice. Seems like the past is forgotten (if there was ever any truth to it) and the two divas are now the best of friends. Or they are just desperate for hits, so they had to resort to this... How long do you give them?

What can I say, here's to Gaga and Xtina, and to some new pop girls making headlines (Lorde and Selena, I'm looking at you)!
