Ryan Reynolds has Blake Lively’s back.

The actor praised his “fearless” wife in a Mother’s Day Instagram tribute over the weekend after her headline-making settlement with Justin Baldoni.

“I appreciate this mother beyond measure,” the “Deadpool” star, 49, told his followers Sunday. “She is kind. She is fearless. She’s the absolute love of my life.”

He concluded with a reference to their children — James, 11, Inez, 9, Betty, 6, and Olin, 3.

“To our four little kids,” Reynolds gushed, “she’s the life of their love.”

While the Story upload did not include pictures of the couple’s brood, who remain out of the spotlight, Reynolds shared two photos of himself and Lively.

The”Green Lantern” co-stars, who wed in 2012, hugged at Niagara Falls in one of the snaps and sat side-by-side on patio chairs in the other.

Reynolds’ post came one week after Lively settled her and Baldoni’s bombshell lawsuit.

The “Gossip Girl” alum accused Baldoni, 42, of sexual harassment and attempting to destroy her reputation in December 2024.

She sued her “It Ends With Us” co-star the following month, and the pair were set to go to trial on May 18.

However, their contentious legal battle came to a shocking end on May 4 when the former colleagues issued a statement.

“The end product — the movie ‘It Ends With Us’ — is a source of pride to all of us who worked to bring it to life. … We acknowledge the process presented challenges and recognize concerns raised by Ms. Lively deserved to be heard,” they wrote.

The joint statement noted they “remain firmly committed to workplaces free of improprieties and unproductive environments.”

Neither Lively nor Baldoni made a cent in the settlement, while their lawyers earned $6 million.

Their legal woes, however, are not over due to Lively seeking attorneys’ fees and damages over Baldoni’s $400 million countersuit, dismissed last year.

Lively, who appeared at the Met Gala in the wake of the settlement, considers the outcome a “resounding victory,” according to her legal team.

Baldoni’s lawyer, meanwhile, denied this by asking what “defeat” looks like since Lively “filed a claim for $300 million and she ended up with nothing.”

While Reynolds has yet to speak out on the settlement directly, he and Lively have put on a united front since the legal war began.
