Mr. & Mrs. Smith 2.0? Justin Timberlake has a sexy love interest in his steamy new music video for his latest "TKO" single -- and it's not wife Jessica Biel.

The 32-year-old singer enlisted the help of 24-year-old actress Riley Keough, the granddaughter of Elvis Presley and daughter of Lisa Marie Presley. The Ryan Reichenfeld-directed seven-minute video shows Timberlake's tumultuous relationship with Keough. In one scene the two are shown cuddling on a couch, and in another Keough is seen driving a truck down a dirt road with Timberlake dragging behind.

"Baby, now I really know what we're fighting for," Timberlake sings. "This rematch sex is amazing/ But nobody wins if somebody's heart is slow."

In one particularly steamy scene, Timberlake and Keough have makeup sex in the kitchen following an explosive fight. The singer picks up the gorgeous brunette actress, who is wearing only a white dress shirt, and places her on top of the kitchen counter. The two then engage in a passionate makeup session that is reminiscent of the hot kitchen scene between Brad Pitt and Angelina Jolie in the 2005 film, Mr. & Mrs. Smith, where the couple fell in love in real life.

Timberlake married actress Biel, 31, in October 2012 after about five years of dating. Keough was previously engaged to actor Alex Pettyfer in 2012, and was recently rumored to dating pal Kristen Stewart's ex-boyfriend Robert Pattinson.
