Britney Spears gave us a sneak peak at her upcoming forthcoming album, Femme Fatale, by releasing its second single, “Till the World Ends,” yesterday. Apparently my least favorite singer, Ke$ha, also helped Brit out with this song a bit. After listening to the song you definitely can see the Ke$ha resemblance. Spears also stopped by the Ryan Seacrest’s radio show today (March 4), and admitted that the song just felt right for her as soon as she heard it.

” ‘Till the World Ends’ is fun! It’s fun. I like it. It’s good energy,” she said of the song, which was produced by Dr. Luke, Max Martin and Billboard. “I’m a vibe person, and I think I love good-mood songs, and if it puts me in a good mood, it clicks for me.”

As for her upcoming album, which already produced a chart-topping single, “Hold It Against Me,” she told Ryan, “I think it’s my best work yet. I listened to it on the way over here. It’s definitely something you want to work out to. … And I’m a dancer, so it’s definitely something I can work with.”

In addition to talking about the album, Brit Brit also announced her plans for a summer tour. She also filled everyone in on her current workout routine. “I have a trainer. I go on the treadmill for 30 minutes and we do a lot of cardio, running,” she explained. “He kicks my butt. You pay to hate your trainer!”

So what do you all think about Brit’s new song? It’s ok…I like it but I’m not in love yet, maybe it will grow on me?
