Okay, this sounds crazy because I don't even know the lyrics and have only heard it a few times on the radio. It's a slow jam that came out probably in 2009 or late 2008. It's a duet and the female lead sounds kinda like Fergie, but I don't think it's her. It's something about "I think I'm in love with you" or something about love (of course it's a slow jam) but I heard this song while out dancing in December and am dying to hear it again. If anyone can help or even list a few titles that might be it, I'd be forever grateful! Duet, slow jam, came out within about 12 to 18 months, strong female lead vocals and that's all I got. Thanks!
