During an episode of "The Ellen Show", the 34-year-old star, who tied the knot with Timberlake in October 2012, praised him for being so flawless, reported Femalefirst.
"Literally every year we're married I'm looking for that thing that he really sucks at," Biel said.
The couple recently sparked speculation that they are expecting a second child when both were spotted dancing at a basketball game and Timberlake cradled Biel's stomach with his hands.
