Heather Morris is really starting to show! The 26-year-old pregnant Glee star was spotted stepping out to take her dog -- and her baby bump -- for a walk in L.A. on Tuesday, May 14.

Morris showed off her growing belly in a American flag tank top and tiny gray shorts during the outing. The first-time mom-to-be put her hair in a ponytail and wore little makeup for the casual stroll.

Morris still hasn't publicly commented on her pregnancy. She has been keeping a low profile, and skipped this year's FOX Upfronts with her Glee costars in NYC on May 13.

The actress previously told Fitness magazine in 2011 that she puts her relationship ahead of her career. "I want to marry him so bad. That's what I really care about," she shared. "I want to marry Taylor and have kids with him. I love acting, but if it affects my relationship, then I won't continue doing it."
