The mother-of-five might be one of the most recognisable women in the country, but she guards her privacy fiercely, only make a select handful of public appearances throughout the year. You're more likely to find her supporting a charity close to her heart or backing a friend on a big night, but she made an exception as she hit the red carpet for Wednesday night's Irish premiere of The Shape of Water.
Wearing all-black, she looked effortlessly chic in a masculine tailored suit, combat boots and her trademark tousled hair tied up loosely.
Ryan must surely be beaming because of the success of her children - Bonnie, a singer and makeup artist, Rex, an actor, Babette, a model, Lottie, a radio broadcaster and son Elliott, who has chosen a more private career.
Last night's screening at Dublin's Lighthouse Cinema was also attended by former Miss Ireland Holly Carpenter and good friend Dillon St Paul, who featured on BBC's The Apprentice last year, former Xpose host Lisa Cannon and RTE presenter Blathnaid Treacy.
