Blake Lively and Ryan Reynolds started as friends and are now married with four kids. Here's how they met and a timeline of their relationship.

Justin Baldoni has sued Blake Lively and her husband Ryan Reynolds, alleging that the Hollywood couple sought to “destroy” him and his career, after hijacking his film, “It Ends With Us.”

Baldoni, in a lawsuit filed in New York federal court on Thursday, alleges extortion, defamation and claims related to breach of contract, among several others. He’s joined by his film studio, Wayfarer, and its chief executive Jamey Heath, and their public relations representatives, Melissa Nathan and Jennifer Abel. They seek at least $400 million.
