Hillary Clinton turned heads when she greeted actors backstage at the Broadway play "Ain't Too Proud: The Temptations Musical" at The Imperial Theatre on Thursday, Dec. 12, in New York City.

The former first lady's plump cheeks and youthful appearance prompted some to wonder if she went under the knife in preparation for her 3rd run at the White House.

Clinton was wrinkle-free as she greeted actors with her husband, former President Bill Clinton.

Many say she looks a lot difference today than she did in 2016 when she lost the election to President Donald Trump.

Observers also noticed her smooth skin when she spoke at the Jewish Labor Committee's Annual Human Rights Awards Dinner in NYC on Monday.

Aesthetician Dr. Ross Perry tells Dailymail.com's FEMAIL that Clinton has been "genetically blessed" with good skin - but he says her youthful appearance could also be a result of Botox, injectable dermal fillers and dermabrasion treatments.

Clinton's camp is dropping hints that she will enter the 2020 presidential race after more Democratic hopefuls drop out.

California Senator Kamala Harris is already gone and NJ Senator Cory Booker is said to be making his way to the exit door.

Some political analysts say Clinton is a long shot for the nomination if she enters the 2020 race.

But others say Clinton is former President Barack Obama's choice for the nomination. They say Obama believes Clinton is his best chance to take control of the White House for an unofficial third term.

That's why his office is in Washington, D.C. rather than in his hometown of Chicago.
