US star Heather and her boyfriend Taylor Hubbell became proud parents to Elijah in September 2013 and she has since been on maternity leave.
However, Heather was back playing ditzy Brittany Pierce at McKinley High School yesterday alongside her co-star Lea Michele for Glee's 100th episode.
Lea has now shared a picture taken on the set of the American musical TV show, in which she is posing alongside Heather and fellow co-star Jenna Ushkowitz, who plays Tina in Glee.
Tweeting it to her fans, she commented: "Love these ladies! @JennaUshkowitz and #Hemo! So nice to have Heather back! #glee100thepisode."
Heather met her longtime love Taylor in high school, and her pregnancy news broke in 2013.
Away from Glee, Heather prefers to stay away from the limelight.
