Leighton Meester, Adam Brody to be first time parents

London: Leighton Meester and Adam Brody are expecting their very first child.

The 29-year-old 'Gossip Girl' star was recently spotted sporting a growing baby bump in a tight grey tank top with a plaid shirt, as she stepped out for a lunch date in Los Angeles, the Mirror reported.

While Brody had joked last summer about having a huge family, Leighton had recently told a publication that she was ready for grown-up stuff and knew kids were next.
