After 13 years of marriage, Ioan Gruffudd abruptly left his wife Alice Evans earlier this year.

This week, Evans has publicly accused Gruffudd of having an affair behind her back for three years.

"So it turns out that my husband, after two years of telling me I’m a bad person and I’m not exciting and he no longer wants to have sex with me and he just wants to be on set abroad… has been in a relationship for THREE years behind all our backs. Good luck, Bianca," the 50-year-old wrote on Twitter.

So, who exactly is Bianca and how did things get to this point?

Alice Evans and Ioan Gruffudd’s relationship.

The couple met in 1999 on the set of102 Dalmatians, with Gruffudd playing the animal shelter owner and Evans starring as Cruella de Vil's probation officer.

The pair became engaged on New Year's Day in 2006 and married one year later.

They share two children together, Elsie, eight, and Ella, 12.

Before their second daughter's birth, Gruffudd, 48, told People he had “basically been the best husband in the world,” during his wife’s second pregnancy.

“You go from being lover to husband, lackey, taxi driver. You just have to have so many caps on. Listen, it's a blessing that I am here, at home not working, being able to be there for her,” Gruffudd said at the time, before adding: “It's been tough.”

“I’m sure we have no idea what we are heading into. But we both love each other so much and really hope that we will create an environment of love and happiness.”

They announced their separation in January of this year.

At the time, Evans shared the news via Twitter, saying she had no idea why her husband of 13 years had left her.

“My beloved husband/soulmate of 20 years, Ioan Gruffudd, has announced he is to leave his family, starting next week,” Evans posted in a since-deleted tweet. “Me and our young daughters are very confused and sad.”

She continued: “We haven't been given a reason except that he 'no longer loves me.' I'm so sorry.”

According toThe Sun, she later explained why the post was no longer available on her profile.

"Hi there," she began.

"I didn’t delete the tweet from a few hours ago about him leaving. He did. From my account.

"And hell yes when I am being gaslit and mentally tortured then hell yes I will wash my linen in public."

The couple later gave a joint statement to US Weekly, saying: "As you can imagine, this is an incredibly difficult time for our family and we remain committed to our children. Thank you for respecting our privacy."

In February 2020, Gruffudd admitted to The Guardian that his marriage had been struggling for a number of years.

“I think we’ve struggled the past four years, making time for each other because physically we’re apart.”

The affair allegations.

This week, Gruffudd went Instagram official with his new girlfriend, actress Bianca Wallace, captioning the post: “Thank you for making me smile again.”
