The Big Bang Theory star attended The Amanda Foundation's Annual Bow Wow Beverly Hills Halloween event in Los Angeles last night (27 October) with her husband-to-be and couldn't resist cuddling up to some canines while there.
Wearing a smart ensemble of black tailored trousers, black heels and a floral peplum top, Kaley got up close and personal with a few of the adorable dogs, including two little pooches wearing colourful jackets. Aww!
Being an honoree guest for the evening, Kaley's fiancé was on hand to offer support and the couple looked super loved up as they posed for pictures.
Professional tennis player Ryan sported a dapper smart-casual outfit, wearing a velvet black jacket, a maroon T-shirt and dark jeans.
He proposed to Kaley last month, following three months of dating and just days after their red carpet debut at a pre-Emmys party.
It's no wonder the future Mr and Mrs Sweeting were eager to make an appearance at the Annual Bow Wow Beverly Hills Halloween event on Sunday, since they are proud owners of two gorgeous dogs themselves.
Kaley posted a cute snap of herself, Ryan and their pooches over the weekend and wrote: "Impromptu photo shoot w my little family :) @ryansweething".
