Despite Lady Gaga's flamboyant career, she managed to keep her relationship with Kinney private.

Aside from "Chicago Fire," Kinney also appeared in "Breakout Kings," "Shameless," "Dating Rules From My Future Self" and "The Vampire Diaries." He was born in Lancaster, Penn. and moved to Hawaii after dropping out of West Virginia University, according to USA Today.

Among the biggest projects Kinney had was the 2014 hit film "The Other Woman," which starred Kate Upton, Leslie Mann and Cameron Diaz, who herself just got married on January 5, 2015 with musician Benji Madden.

After a 17-day engagement, Diaz and Madden tied the knot at "The Other Woman" actress's home in Beverly Hills, Calif.

In 2014, Diaz and Mann admitted to playing a prank on Upton while she was sleeping on the plane. The two said during their interview on "Late Night with Seth Meyers" on April 25, 2014, that they draw a mustache on the 21-year-old supermodel and actress who was deep asleep while thousands of feet above the ground.

According to Mann, Upton was fast asleep so she and Diaz were up and thought what they could do until they decided to draw a mustache. Diaz described how Upton was sleeping like a little child while she was drawing on her.

After drawing the mustache, Diaz and Mann felt so guilty about taking pictures so they joined in on the prank by also drawing mustaches on themselves.

Mann, 42, is married to Judd Apatow for 18 years.
