VIDEO: Half-naked Lily Allen dances in her Spanx

Lily Allen shares everything with her fans, including a half-naked video. Watch her latest Instagram clip with a bit of dancing with Spanx.

Even celebrities wear Spanx. That’s what Lily Allen is proving after posting an Instagram video of herself dancing topless while wearing her Spanx bottoms.

The video shows the mother of two dancing in front of a mirror in her dressing room to Drake’s “Started From the Bottom.” She captioned the video, “Cool mum #drakespanxdance.”

Perhaps Allen will start a new internet sensation with the hashtag #drakespanxdance.

The “Hard Out Here” singer looks amazing after giving birth to her second daughter, Marnie Rose, in January 2013. Even though she’s only wearing her undergarments and covering her breasts, the best part of the video is watching the man in the corner who doesn’t even register the hilarious dance in front of him. He kept his head buried in his smartphone.

The yellow-haired singer was in Brussels performing on Tuesday, but she’s proving she’s still one hot mama. It’s a big improvement since earlier in the month she shared photos of her hospitalization after becoming dehydrated from a bout of projectile vomiting.
