During her chat with the talk show host on Friday night the 28-year-old starlet, who is married to Ryan Reynolds, came armed with a hilarious video of James inspecting the life-sized cardboard cut-out of Jimmy that she was given the last time she was on his show.
In the footage, James can be seen showering the Jimmy cut-out with loving kisses.
“Is that Jimmy?” Blake asks. Before continuing, “Where’s your dada?”
Baby James then points at Jimmy and calls him “dada.”
Cutting back to Blake and Jimmy in the studio, the pair chuckled before Jimmy joked, “I hope Ryan [Reynolds] isn’t watching tonight.”
“Even backstage she goes [to you] 'dada'. I think I should do a paternity test right now on air,” Blake confessed.
“This is the wrong show, you’re not on Maury [Povich],” Jimmy said.
James’ confusion over the identity of her father isn’t the only adorable thing the young tot has been getting up to!
According to Blake, her first child is also struggling to grasp a few words.
“She says ‘shump’ for jump, ‘shtand’ for stand and if she wants to sit down, it’s ‘s---,’” Blake shared.
“But I will take that any day over when we take her to the park and we take off her socks. For some reason she doesn’t have her ‘sh’ for socks, she has a ‘c’ for socks.”

Meanwhile the blonde beauty, who is currently promoting her latest film Café Society, also opened up about her second pregnancy, admitting the balmy summer weather in the Big Apple was proving a challenge.
“It should be illegal to be pregnant in New York in July,” the Gossip Girl stunner explained.
“I swear, I’m going to make my water break just so I can cool down.”
