Guess which pop star is dancing around topless in her spanx?

It’s all about the spanx, ladies! And this pop diva isn’t shy about flaunting hers.

That’s yummy mummy Lily Allen strutting her stuff in the skin colour control briefs on Instagram. Check it out in the video above.

But Lily isn’t your regular mum, she’s a “cool mum”, as she clearly demonstrates while singing along in a chipmunk voice to Drake’s “Started From The Bottom.”

Yep, we’re certainly seeing a whole lotta bottom there, Lil.

After the impromptu underwear dance, the 29-year-old slipped into a sexy silver dress for her concert in Brussels. Check out how hot she looks:
