Glee actress Lea Michele has given birth to a baby son, according to People.

The 33-year-old and husband Zandy Reich are said to have welcomed the youngster, whom they have named Ever Leo, on Thursday.

"Everyone's happy and healthy, and they're extremely grateful," a source told the publication.

"He's been an easy baby so far."

The last few months of Michele's pregnancy have been dogged with allegations about her poor behind-the-scenes behaviour on Glee and other productions.
