The Twitter post to her more than 3.5 million followers appeared to be a swipe at former New York City Mayor Mike Bloomberg's run for the 2020 Democratic presidential nomination.

Biden thanked Cher, who is completing a three-year Las Vegas residency this month, in his own social media message. The former vice president also made his own pitch for hitting the Vegas stage ahead of the Nevada Democratic caucuses on Saturday.

In a 2018 interview with ITK, Cher called Biden a "really great man."

"I would love to see [Biden run] with someone young," Cher said of the 77-year-old ex-VP, when asked at the time about who she'd potentially root on in the 2020 race.
