Two of Hollywood's biggest talents steal the show at a Billy Joel concert.

Two of Hollywood’s coolest women, Jennifer Lawrence and Amy Schumer just lived out every 80s girl’s dream.

(And probably one of Billy Joel’s dreams if we’re being honest…)

After spending most of the night partying back stage at Billy Joel’s Chicago concert last Thursday night, the two friends eventually made their way to centre stage when Billy Joel began singing, ‘Uptown Girl.’

The two BFFs, who appparently consider each other creative soul mates, can be seen running on stage, with Schumer climbing atop Joel’s black grand piano shortly afterwards.

Lawrence quickly took this opportunity to cheekily kiss her best friend’s feet whilst she was mid-climb before joining her for a boggie on the shiny black piano. The whole scenario was documented in a video which Schumer posted across her social media platforms.

Towards the end of the song the 66 year-old ‘Piano Man’ is seen to be serenading the two blonde beauties.

Now, Taylor Swift has been doing the dramatic celebrity reveal for the past couple of months, but having two of the world’s most sought-after talents climbing up onto your piano is probably next level.

It leaves us wondering, if we go to a gig and DON’T see a random celebrity run on stage, have we wasted out $150?

If you could dance on stage at any celebrity concert, who would it be?
