It’s been nearly six months since Glee’s Heather Morris gave birth to her son, Elijah, but we still haven’t seen much of the 27-year-old star. The little man arrived on September 28, 2013, and we really haven’t heard a peep from her since then.

Except for a few Instagram photos posted by fans, Heather’s been flying majorly under the radar. The actress has been taking time off to enjoy being a mom, but it looks like she’s also been logging some time at the gym!

For her first public appearance since giving birth, Heather stepped out for the Glee 100th Episode Celebration on Tuesday, March 18. Showing off her toned arms and lengthy legs, the actress looked slim and stunning in a black patterned dress with ankle-strap platform heels. Heather was joined by her fellow castmates at the Chateau Marmont, including former originals Dianna Agron and Mark Salling.

For those you that didn’t tune in for the 100th episode, Heather made her grand return for the first time since the end of Season 4. (Pregnancy definitely has a way of cutting a storyline short!) Heather’s character Brittany reunited with Santana, planted a sweet one on her lips, and told her that she knows she’s the only one for her.

With Demi Lovato leaving Glee as Santana’s girlfriend, Dani, this definitely opens up the door for a Brittana reconciliation. ‘Shippers rejoice!
