Amber Riley just got some serious competition, but not from any of her fellow Dancing With the Stars finalists! The Glee actress’s DWTS partner, pro Derek Hough, got down and dirty with actress Kate Hudson over the weekend as the two whipped out an impromptu dance routine at a Cuban restaurant in Hollywood.

The Oscar-nominated actress busted some serious moves alongside Derek at the Cuban restaurant and lucky for us, a watchful patron caught it all on tape.

Kate has been receiving private lessons from Derek for months now because how else would a celebrity learn the tango other than having a four-time Dancing With the Stars winner come to their home and tutor them? No Darrin’s Dance Grooves for this leading lady.

“I’ve been working with Kate Hudson a little bit lately for fun just dancing for fun, giving her some lessons,” Derek told E! News back in August. “She’s become a good friend and she’s great.”

Sadly, Kate won’t be repaying the dance lesson favors by appearing on DWTS anytime soon — although we definitely think she should reconsider.

“I would love for her to do the show, but she would never,” Derek said. “She’s fantastic. But I want her maybe to do a guest spot.”
