“Everyone nicknamed [my mom] Kathy ‘I’ll do anything for my daughter’ Wilson,” the 35-year-old actress confessed.
"She used to do this thing she coined 'girlfriends,' which meant she'd pick myself and my girlfriends up from school, we'd roll down the windows, and we'd listen to the Mermaids soundtrack at full blast," Wilson continued. "So all my friends would sing and we'd go to 7-Eleven and she'd be like, 'Get anything!' And it was so freeing. My mom would always roll up in the craziest outfits. Like, she would rock a purple Speedo one-piece bathing suit with a fur coat and Birkenstocks, just like, 'Here I am!'"
Wilson’s mother died unexpectedly in 2005, her death certificate stated she had died of obesity.
"My mom struggled with her weight a ton and so when I saw that, I was so devastated," Wilson revealed. "I know it's quote-on-quote a medical term, but for a woman, I just felt like, this is so heartbreaking that someone's life is reduced to obesity. I was bereft. It hurt my feelings so deeply for my mom."
The Marry Me actress went on to explain that her mother’s death lead to a series of emotions. "Why couldn't you get a handle on your eating?” she recalls thinking to herself. “And there was anger about … what I perceived to be careless treatment of herself."
Earlier this year, Wilson told ET there's definitely hope for a revival of the cult hit comedy, Happy Endings, which originally aired from 2011 to 2013 on ABC.
"There's interest," Wilson teased. "Someone even called my husband [David Caspe], who created it, and basically said, 'I'm a private investor, I would love to pay for a movie' … we were like, OK... now private citizens are coming off the streets!"
