The British actress, 49, and her youngster visited London's popular department store Harrods where they tried on some goofy hats, reported Us magazine.
"With my little man at the Disney Cafe @Harrods," Hurley captioned the selfie with her son via Twitter, who wore Mickey Mouse ears with a Fantasia hat while she sported Minnie Mouse ears with the character's signature red polka-dotted bow.
The bikini designer was visiting the department store to check up on her swimwear line, which had its own display.
"@Harrods thank you to the lovely staff at the swim department. Elizabeth Hurley Beach looking great!," she captioned a photo of herself posing in front of her line.
