Blake Lively and Ryan Reynolds reportedly will not find out the gender of their coming baby, according to Us Weekly.

“Blake and Ryan aren’t finding out what they’re having,” the insider tells the magazine. “They want to be surprised!”

The source added that the actress is “[feeling] super relaxed and mellow.”

The 27-year-old mom-to-be announced her pregnancy last month on her lifestyle website Preserve.

In the post entitled Preserve Celebrations: Falling for Family, Lively, who is expecting her first child in the spring, shared a photo of herself cradling her growing baby bump.

“With a new baby on the way there is so much to do!” Lively wrote on the post. “But before experiencing the joy of 3 a.m. screams, seemingly impossible amounts of poop and having a favorite shirt covered in reflux … there are presents to open, onesies to dye, there is cake to serve, advice to be shared and all around celebration to be had. And that we did.”

“He’s always good to me,” said The Gossip Girl. “That’s like a jerky thing to say because you want to be able to complain about your husband and be that person, but he takes pretty good care of me.”
