Phil Collins, Alice Cooper, Mick Fleetwood and Graham Nash were among the artists posting Happy Valentine's Day greetings.
Collins, plugging his 2004 Love Songs compilation, posted a video of him saying, "Well, it's February 14th again, and because your other half didn't buy you a Valentine's card, you're stuck with a message from me. Happy Valentine's Day."
Mick Fleetwood also shared a video, but his was more in the agricultural vein as it shows him giving a rose to his pet pig Tilly.
