The mom-of-three watched Zuma’s soccer game before arranging via FaceTime for Blake to pick her and her three kids up, an eyewitness claims.

As In Touch previously reported, Blake “really admires” Gwen’s commitment to her kids and enjoys spending time with them as well.

A source said, “Blake absolutely loves kids, and is a big kid at heart. Having a girlfriend with kids doesn’t faze Blake at all.”
