Bradley Cooper and Irina Shayk 'Spent a Lot of Time Apart' Before Split: He's 'Into His Work'

Bradley Cooper and Irina Shayk have split after four years together

Bradley Cooper and Irina Shayk drifted apart before their split became public.

“[Irina is] not focused on the celebrity part, or on the fame — she just wants to protect her family,” a source tells PEOPLE of the supermodel. “Bradley is very into work and is trying to take advantage of every career opportunity right now.”

Adds the source, “They spent a lot of time apart.”

While the two were spotted enjoying a date night in New York City in April, they were more often than not working on their own projects.

A different source tells PEOPLE, “They were living totally separate lives.”

“If he was in L.A., she’s out of town, and if she was in town, he was out of town,” says the insider.
