The 30-year-old actress commented Thursday after Reynolds visited Jackman at his Laughing Man coffee shop in New York.
Reynolds had shared a photo on Instagram of himself with Jackman at Laughing Man. The actor jokingly said in the caption that he had followed Jackman to the cafe.
"Ran into this guy at his coffee shop, @laughingmancoffee. And by 'ran into' I mean I followed him there," he wrote.
Lively remarked in the comments about the large gap between Reynolds and Jackman in the picture.
"Is the extra distance between you supposed to convince me that you DON'T love him more than me?? Nice try," the actress joked.
Jackman also shared a photo with Reynolds on his own account.
"We put out word that @laughingmancoffee is looking for a new barista ....and, @vancityreynolds shows up? #makeeverycupcount," the actor wrote.
Reynolds and Jackman play Deadpool and Wolverine in the X-Men movies. Reynolds co-starred with Jackman in X-Men Origins: Wolverine, and expressed interest in another collaboration in an interview this week.
"He and I have great chemistry, and I love goofing around with him," the actor told Entertainment Weekly. "I would love to see that someday."
