United Kingdom, Feb. 4 -- Blake Lively has been "surprisingly calm" amid her legal dispute with Justin Baldoni.

A source told PEOPLE: "Blake is surprisingly calm and just tries to focus on family life."

The insider explained: "She's in constant contact with her team. She sees the whole lawsuit drama as a necessary bump, but she's not letting it take away from her main focus, which is her children." ...
