Is Megan Fox pregnant again?

Story highlights

  • Fox appeared to sport a baby bump on the red carpet Monday
  • She and estranged husband Brian Austin Green have two sons

(CNN)Megan Fox let her belly do the talking Monday night.

The actress showed up on the red carpet at CinemaCon in Las Vegas to promote her new film, "Teenage Mutant Ninja Turtles: Out of the Shadows." Her black Versace dress showed what appeared to be a baby bump.
    Fox -- known as one of the more private celebs -- has not announced a pregnancy.
    The mother of two and husband Brian Austin Green -- best known for his role on "Beverly Hills 90210" -- filed for divorce in August. The pair were together for 11 years and married for five.
    The "Transformers" star told People on Monday that filming while being pregnant is difficult.
    "I'm always in the process of having a baby and looking like I didn't have a baby," she said.
    The actress revealed to another outlet that her children with Green have no idea what she does for a living.
    "I try to keep (the children) from television and movies for the most part," Fox told E!. "Because I think screen time, any sort of screen whether it's television, iPad or iPhone is really bad for their brain development so I try to remove that from their lives. Also I want to deter them from ever being a part of social media cause I think it's detrimental to a child's self esteem."
    Fox famously left Twitter in January 2013 after tweeting "5 days on Twitter and I have yet to discern it's purpose. #WhatIsThePoint ???"
