Blake Lively had that mother's glow as she surfaced after her baby's birth. Meanwhile, her husband Ryan Reynolds and the "Gossip Girl' actress are still silent about their daugther's name.

Since giving birth about six weeks ago to a baby girl, Blake Lively has made herself scarce in terms of public appearances. However, she posted a photo of herself on Intagram hugging Mario Testino, who is being billed as "photographer to the stars."

"Blake certainly looked radiant with her burnished locks spilling around her smiling face, wearing a stylishly casual black zip-up jacket that gave a hint of her trimmed down waistline," Daily Mail said.

The 27-year-old mother captioned the image: "The one. The only. @mariotestino."

Blake Lively, however, didn't address all the speculations regarding the name of her baby with her husband Ryan Reynolds.

David Letterman in his talk show tried to bait Ryan Reynolds into spilling his baby daughter's name.

"Here's a beautiful name - Sophia... is that your daughter's name?' Letterman asks the actor.

"No, it's not at all, not even close," Ryan Reynolds tells the host.

Letterman then prods, "Is this getting on your nerves?"

"No, not at all. I can go all day," Ryan Reynolds replies. "I'm this close by the way, so keep going."

Letterman proceeded to list down names including Olivia, Madison, Emma, Ruth, Abigail and Isabella.

Ryan Reynolds can only quip, "I should've worn my cup. I didn't know I was gonna get busted this hard."

Previously, Ryan Reynolds told USA Today, that he and Blake Lively hasn't been getting too much sleep these days.

"It's still so new that it's hard to conceive being away for more than seven hours at a time," he said. "I had to go to Sundance this last week. I was more excited to get a good night's sleep. It was borderline pornographic for me."
