Pretty and pregnant! Megan Fox, who is currently expecting her second child with Brian Austin Green, stepped out for a doctor's appointment in Beverly Hills on Tuesday, Nov. 26, flaunting her expanding baby bump. See more pics of her baby bump!

The Transformers star, 27 -- accompanied by her husband, 40, and son Noah, 14 months -- looked casual and comfortable in black leggings, an oversized gray shirt and green utility jacket. On her feet, the pregnant star opted for bedazzled black UGG boots, as she shielded her eyes behind a pair of shades.

While Fox cradled her baby bump in a form-fitting black dress at the launch of Avon's #SeetheSigns of Domestic Violence Campaign on Nov. 22, her outfit on Tuesday did very little to conceal her protruding tummy.

"I've had rough first trimesters," she told Us Weekly at Avon's NYC headquarters prior to Friday's event. "But once you get into the second, it's fine after that." The expectant actress, who confirmed her second pregnancy in August -- 11 months after she and her husband welcomed Noah -- told Us that she was "better now," after sharing that her second pregnancy was "rough in the beginning!"

The This Is 40 actress is also stepmom to her husband's son Kassius, 11, from his previous relationship with actress Vanessa Marcil. Fox wrapped up filming for 2014's Teenage Mutant Ninja Turtles, in which she will play the role of April O'Neil -- a reporter and close friend of the pizza-loving, crime-fighting Turtles.
