Karina Smirnoff Seeing Orange Is the New Black's Pablo Schreiber

When DWTS and OITNB collide! Karina Smirnoff is romancing Orange Is the New Black's Pablo Schreiber, multiple sources confirm exclusively to Us Weekly.

The Dancing With the Stars pro and Schreiber, both 36, were spotted getting cozy together during the iHeartRadio Music Festival in Las Vegas on Friday, Sept. 19.

"They were very flirty, affectionate and touchy-feely during the entire time at the show," an eyewitness tells Us. "It looked like they had great chemistry."

The pair stayed close to one another, laughing and dancing during performances by the Zac Brown Band and Usher. They continued their fun backstage and partied afterwards at Beacher's Madhouse. (Pablo is the younger half-brother of actor Liev Schreiber.)

Smirnoff was previously engaged to former DWTS pro Maksim Chmerkovskiy until their split in September 2009. She's also been linked to Mario Lopez and Detroit Tigers baseball player Brad Penny.

Schreiber, who plays corrections officer George "Pornstache" Mendez on Netflix's smash hit Orange Is the New Black, separated from his wife Jessica Monty in January after seven years of marriage. The exes share two children.
