Diane Keaton flustered on TV as pop crush Justin Bieber surprises her with a hug

Veteran actress Diane Keaton has got the hots for Justin Bieber and made it clear she wants to date him on TV.

At 69, the Annie Hall star is 48 years older than the singer, but she's not about to let age get in the way of her romance dreams after meeting the Baby hitmaker during a taping of The Ellen DeGeneres Show this week (beg09Nov15).

Keaton, who was promoting her new film Love the Coopers and her The Keaton wine line, was thrilled when DeGeneres asked her if she was a fan of Bieber's music as she flashed shots of the singer's Calvin Klein underwear campaign on a large screen.

The flustered actress said, "I like that boy... That is gorgeous."

And as the shots kept changing, Keaton added, "Oh no, stop it! That's not possible", swooning at the pop star's good looks and toned physique.

Bieber, who was preparing to perform on the show, which aired on Friday (13Nov15), decided to surprise his famous fan and ran out to hug her as Keaton squealed and attempted to steal a kiss.

As he dashed backstage, the actress turned to host Ellen and added, "That's real beauty!"

"Do you think he'll ask me out later...?" Diane quipped before getting serious and asking, "Do you think I have a chance?"
