Blake Lively shares Instagram photo with famed photographer

NEW YORK, Feb. 6 (UPI) -- Blake Lively took to Instagram Thursday to post her second photo since giving birth in December, and much like the first picture, it isn't of her and Ryan Reynold's newborn daughter.

Instead, Lively posed with legendary fashion photographer Mario Testino, who has collaborated with the actress several times int he past. Lively didn't share many details about the snapshot in the caption, and simply wrote: "The one. The only. @mariotestino" along with several heart-eyed emojis.

Testino also shared the photo on his account, and wrote: "GREAT DAY WITH THE GORGEOUS @BLAKELIVELY."

While neither of them have addressed the activities that took place during their encounter, some commenters have pointed out, Testino and Lively were likely working on a photo shoot.

The Gossip Girl star, 27, welcomed a baby daughter with Reynolds, her husband since 2012, sometime in December. The actress told People magazine later that month she didn't feel motherhood was a big change because she "always felt like a mama."

Both Lively and Reynolds have kept all details about their newborn -- including her name -- under wraps. Reynolds recently dismissed rumors that the baby was named Violet while promoting his upcoming film The Voices adding he didn't "want to get into that."
