Lily Allen is a cool mom. Don't believe her? Well, check out this video of her dancing topless to Drake's "Started From the Bottom"! The 29-year-old Brit singer took to Instagram yesterday to share a funny video of her getting down to the hip-hop jam while topless and wearing only Spanx. In addition to her amusing new dance videos, Allen also shared some cute selfies recently with some A-list stars. The "Air Balloon" crooner posed for a cute pic with Harry Styles a few days ago, as well as Chris Martin. She also snapped a shot with Pharrell Williams.
