The longtime couple have been together for 13 years and married for 12

Tammy, who is a mother of four sons including Ryan, her youngest child, has attended a number of A-list events with Blake over the years.

Most recently, she was seen in attendance with her son and her daughter-in-law at the latter’s movie premiere of It Ends With Us on Tuesday.

And sure enough, Blake and Ryan have proved that their marriage has only strengthened with time even as they prepare to go head-to-head at the box office with competing films.

Recently, Ryan’s film Deadpool & Wolverine premiered, and the Gossip Girl alum gushed over her husband and how proud she is.

The pair, who have been married since 2012, are parents to James, nine, Inez, seven, Betty, four and 17-month-old Olin.

Ryan also recently opened up about their marriage and said the secret to their successful and long-lasting marriage is that they are ‘genuinely rooting’ for each other.

Blake added: ‘My husband calls me his knight in shining armor, which I think is so sweet, because we only hear about men being that.’

She joked that her marriage is successful and ‘the only reason I’m with him is to be with her’

She also recalled that they made an agreement when they started dating.

She explained that they ‘made a rule not to work at the same time’ so they could ‘prioritize their personal life.’

And Lively openly displays her affection for her other half in public.

She admitted that she often takes his belongings with her and did so when she was filming her upcoming movie, It Ends With Us.

‘I wore a lot of my clothes and my husband’s clothes,’ she said about when she was working on the romantic drama set to premiere on Friday.

‘I’m like, “Why don’t people like my clothes? Oh because I’m wearing my husband’s clothes.” But I thought it was so cute.’

And while promoting Deadpool & Wolverine with Hugh Jackman, Ryan compared the secret to a successful marriage to their long-lasting 17-year friendship.

‘I think the secret sauce to a long-lasting Hollywood friendship is not to dissimilar to having a partner or a marriage,’ he said.

Blake said that her husband calls her his ‘knight in shining armor, which is so sweet, because we only hear about men being that’; seen in July

Addressing his co-star and longtime friend, he said: ‘I am genuinely rooting for you all the time. I want you to win.’

During her conversation with the outlet Blake also discussed her upcoming movie.

In It Ends With Us, which is based on the same-name novel by Colleen Hoover, the actress plays a woman named Lily Bloom, who gets entangled in a very complicated love triangle.

About the movie, she shared her adoration for her character and the story.

‘I hate the word “inspiring” because it feels so “urgh” — but it is,’ she said. ‘It’s inspiring to see someone experience what they experience and how she comes out of it. It was really important to show that Lily didn’t start at the place where she finds herself at the end.

‘We always see the damsel who then finds her voice,’ she continued. ‘But you can have a voice and you can still be hurt and you can still lose yourself.

She also recalled that they made an agreement when they started dating. She explained that they ‘made a rule not to work at the same time’ so they could ‘prioritize their personal life’; seen in February 2022

‘I wanted to see a woman who had real agency and was spicy, kinda like old-timey movie stars like Katharine Hepburn and Rosalind Russell and Barbara Stanwyck.’

She also noted that she has been told to make sure the characters she portrays are ‘likable’ ones while her husband has never been told to do the same.

‘Every time that I do a movie, the first note is — in the script, in the execution, in the marketing, in the editing — they are like, “We got to make sure she’s likable.” And I went to my husband one day and I said, “Have you ever gotten the note where they’re like, ‘We want to make this guy’s likeable?'”

‘He’s like, “Nobody’s ever said that.” And my husband plays deeply unlikable people — but you love him. Women, they’ve gotta be likable. Why is that?’

It Ends With Us premieres in theaters on Friday, August 9.
