Nick Cannon pining for lost love this Valentine's Day? The talk show host dropped a new song on Monday that serves as a love letter of sorts to his ex-wife, Mariah Carey.In Cannon's new song «Alone» — which tellingly sample's Carey's 1990 single «Love Take Time» — the 41-year-old artist and TV personality belts out some particularly poignant lyrics that allude to him still having feelings for the famed diva.«I say I’m cool when I know I miss it/ I’d trade it all for the case/ If I could have you back/ If I could go back to where we started at,» an apparently emotional Cannon croons on the track.Cannon shared the song to Twitter and wrote in the post, «This is for anybody else who is #ALONE on Valentines Day… I had to come Raw from the heart on this one. #Broken #Shattered #Toxic #RAW&B #Alone.»This is for anybody else who is #ALONE on Valentines Day… I had to come Raw from the heart on this one.
