There's going to be even more XOXOs in this Hollywood family!
E! News can confirm Leighton Meester welcomed her first child with husband Adam Brody.
The happy baby news comes after the A-list couple managed to maintain plenty of privacy during their journey to parenthood.
In fact, fans weren't able to spy the Gossip Girl alumna's glowing baby bump until early July when Meester was spotted grabbing a bite to eat in Los Angeles with a girlfriend. Way to keep the suspense up, girl.

Wearing a basic white tank top and comfy striped pants, the 29-year-old appeared relaxed and at ease as she waited to welcome her new family member into the world.
E! News confirmed back in May that Meester was expecting her first child with Brody. The private pair has never publicly discussed the pregnancy.
To be fair, it shouldn't come as a complete surprise for loyal fans. After all, this couple has been hush-hush about their love affair from the beginning.
Furthermore, the lovebirds have made it a point not to discuss their relationship publicly. Meester, however, previously revealed in an interview with InStyle U.K. that her priorities have changed ever since tying the knot.
"My values have shifted greatly in terms of what I find important," she revealed. "It's my family, my friends and having a personal life. Those are the things that need nurturing."
And she can now add a healthy, beautiful baby to that list. Congratulations you two on your happy news!
Us Weekly was first to report news of the baby's birth.
