Blake Lively and Ryan Reynolds looked happy and in love on the set of the actress’s newest project, “The Age of Adaline,” in Vancouver last month, but according to new reports, the married duo is not on the best of terms due to a recent disagreement over when they should have a baby.

“The couple have come to blows over when to start a family,” reads a report from Thursday which claims the A-list couple is “at war” over their pregnancy plans.

According to sources, Reynolds is keen on the idea of starting a family unlike his actress beau. “He’s 37 and she’s only 26. She says she’s too young and not ready for that step,” said one insider.

Lively is also reportedly at odds with her “The Proposal” star husband over his reportedly “possessive” behavior the drama film’s set. “She’s been doing night shoots and Ryan keeps showing up which infuriates her,” said a source who claimed that Reynolds has amped up his on set appearances due to his fears that Lively may stray with her co-star, Michiel Huisman, 32, of “Nashville” fame. “He appears to be worried,” said an insider.

Despite the online tabloid’s claims, Gossip Cop has since slammed rumors of any marital discord between the actors when it comes to Reynolds alleged cheating concerns. "Huisman is married with a baby and Reynolds is a fellow actor who understands that his wife is playing a role with her co-stars,” reads the report, adding that a rep for Lively has denied the claims, calling the story “b.s.”

This isn’t the first time the former “Green Lantern” co-stars are rumored to have be feuded over pregnancy plans. Last June, Star Magazine published claims that Reynolds had been pushing his wife of almost two-years to get pregnant in contrast with her desires to further her film career.

“Ryan is getting quit impatient about it,” an insider told the magazine, adding that the duo originally had agreed to start their family before Reynolds turned 40. “You can’t blame her for wanting to wait, because she’s so young, but he’s hell-bent on changing her mind,” said a source. “He’s wanted to start a family for years.”

After one-year of dating, Reynolds and Lively married in September 2012 in an quaint wedding in Charleston, S.C. The duo first met while starring as on-screen lovers, Carol Ferris and Hal Jordan, in the 2011 superhero flick, “Green Lantern.”
