'Glee' actress Heather Morris is reportedly pregnant.

The 26-year-old star, who plays cheerleader Brittany S. Pierce in the popular musical TV series, and her childhood sweetheart Taylor Hubbell are expecting their first child together and the couple are delighted to be becoming parents.

A source told Us Weekly magazine: ''She's a little more than three months along and starting to show. It was totally unexpected, but they are incredibly happy and excited.''

The blonde beauty, whose previous career was a backing dancer for pop sensation Beyonce, has previously gushed amount how much she wanted to start a family with her boyfriend and said she was willing to give up acting to focus on her dream.

She said: ''I want to marry Taylor and have kids with him. I love acting, but if it affects my relationship, then I won't continue.''

While they haven't mentioned tying the knot, a close pal of the parents-to-be predicts they will walk down the aisle sooner rather than later.

They said: ''I see it in their future.''

Heather's good news comes shortly after her co-star Cory Monteith, who plays Finn Hudson in the programme, voluntarily checked himself into rehab for ''substance addiction'' and the actor's on-screen and real-life girlfriend Lea Michele has thanked everyone for their support during the difficult time.

She said: ''I love and support Cory and will stand by him through this. I am grateful and proud he made this decision.''
