Hudson's older brother, actor Oliver Hudson, joined the two on their vacation. The actress shared a video on Instagram Stories of the Splitting Up Together star holding hands with his wife, Erinn Bartlett, and dancing.
"He's already drunk," Hudson cracked.
Meanwhile, it appears the 39-year-old actress has been enjoying traveling while she still can. Earlier this week, she shared a snap of her growing baby bump while in Greece, which actually eclipsed her bikini bottoms as she reclined in a chair.
"I think my bikinis pretty cute....#SheBig #HerGurl," she joked.
