Alexa PenaVega & Derek Hough Tango Their Way To The Top the 'DWTS' Floor - Watch Now!

Alexa PenaVega and Derek Hough absolutely kill it during their Dancing With the Stars routine on Monday night (October 12) in Hollywood.

The temporarily-paired duo did the Tango for Switch-Up Week, set to “Pompeii” by Bastille, which earned them a total of 40 points! Judge Carrie Ann Inaba even gave them a standing ovation before their perfect score was announced.

“This week, I’m paired with Derek instead of Mark [Ballas]. Their styles are very different as to how they teach. But I feel like we could not have asked for a better switch up. It has been such an easy transition,” Alexa wrote in her People blog.

She added, “Derek is very, very sweet. He was just telling me, ‘I’m normally way more fun but I’m just drilling this stuff into you and I only have one week so I’m just trying to teach you as fast as I can.’ I was like, ‘I’m having a great time!’”
