Adorable 10-year-old girl jams on-stage with Paul McCartney

She wasn't taking 'no' for an answer.

Meet Leila Lacase, the 10-year-old Argentinian who popped up on stage with Paul McCartney and demanded a jam session.

The pint-sized star was spotted by McCartney during his Buenos Aires gig, as she was holding a sign requesting for the former Beatles star's autograph.

Although when Leila made it to the stage she had something else in mind.

“I want to play the bass with you,” she said.

Taken back by the request, Paul pointed out that she didn’t have her bass with her but that wasn’t stopping Leila though as she pointed to a spare bass that was laying side stage.

Now, you can’t say no to that!

He even let her sing along to Beatles hit, ‘Get Back’.

“Leila, Leila, Leila, Leiia” - a little star in the making.
