AceShowbiz - Ryan Reynolds remains as the biggest support system for his wife Blake Lively amid trying time. A new report claims that the "Deadpool" actor has been the actress' "rock" amid her high-profile legal battle against her "It Ends With Us" co-star Justin Baldoni.

"Ryan is always her rock," a source reveals to PEOPLE. "They have such a special relationship. He's very proud of her in so many ways."

Recently, Ryan apparently hinted at feeling down amid the ongoing drama between Blake and Justin, whom Blake accused of s**ual harassment in a lawsuit. On Monday, December 23, the Canadian-born actor took to his Instagram Story to remind his followers to make donations to SickKids Foundation.

"It's almost Christmas Eve. Last day to donate to @sickkidsvs," so the 37-year-old actor wrote along with the video that also stars Lynda Carter and his 8-year-old daughter Inez Reynolds. "@blakelively and I are matching any donation to $500k. This organization is a sanctuary for so many kids and their parents traversing the unimaginable."

The "Deadpool & Wolverine" actor went on saying, "Thank you @rowlandbb for directing this amazing little piece during a time I really didn't feel like putting the suit on. Thank you @reallyndacarter for your time, grace and talent. Thank you to my daughter for being such a good person despite your dad asking you to swear (for a good cause)."

The post marked Ryan's first statement after Blake sued Justin for s**ual harassment, creating a hostile work environment and conducting a smear campaign against her. Following the bombshell lawsuit, some of Blake's colleagues showed support for her. Among those who relied behind the "Gossip Girls" alum are her "It Ends With Us" co-stars Brandon Skelar and Jenny Slate, her "Sisterhood of the Traveling Pants" co-stars Amber Tamblyn, America Ferrera, and Alexis Bledel, as well as Michele Morrone, who starred alongside Blake in "A Simple Favor 2".
