As she gets ready to launch her residency at The Colosseum at Caesars Palace in Las Vegas next month, Mariah Carey celebrates with her new single “Infinity.” The pop diva sings about a breakup (much like her own with Nick Cannon) on the triumphant tune, which she co-wrote and produced. But despite the love, sometimes forever doesn’t last.

“Close the door, lose the key, leave my heart on the mat for me / I was yours eternally / There’s an end to infinity,” belts out Mariah.

“Infinity” will appear on her greatest hits album #1 to Infinity, due May 18 via Epic Records. The collection also features all 18 of her Billboard Hot 100 No. 1 singles. A music video for “Infinity,” directed by Brett Ratner, is also on the way.

Later today, Mariah will celebrate her Vegas residency with a kickoff event in Las Vegas. The first show starts May 6.
