Mariah Carey Thanks Fans for All the 'E=MC2' Love With 'Impromptu Version' of 'Last Kiss'

Mariah Carey‘s 2008 album E=MC2 unexpectedly topped the iTunes albums chart on Monday morning (April 27), 12 years after its release.

“What is going on?????” the chanteuse tweeted upon hearing the surprising news, before asking fans, “How should we celebrate #JusticeForEMC2? I want to do a singing moment for you! Which song?”

Fans wanted “Last Kiss,” and the icon delivered on Tuesday (April 28). “Woke up yesterday to find out that E=MC2 is somehow the #1 album on iTunes!! On its 12th anniversary no less,” she wrote. “Lambily, you are the friggin’ BEST! I hope you enjoy this impromptu version of Last Kiss.”

Looking fabulous (even at home) in a silk robe and beachy waves, Carey performed an acapella version of the chorus, complete with blowing a kiss to her fans at the end.
