Ireland Baldwin posted new bikini photos on her Instagram with her boyfriend Slater Trout, but this time her father Alec Baldwin made an appearance.

Ireland Baldwin has a strong social media presence, and frequently posts pictures to her Instagram of herself in a bikini and usually with her pro-paddle boarder boyfriend Slater Trout. Yesterday, her famous actor father Alec Baldwin made an appearance in one of her Instagram photos and it looks like her boyfriend and dad are getting along just fine.

In the photo, Ireland, Slater, and Alec are all caught in an action shot as they jump in the air on top of a boat. Ireland is wearing a blue bandeau bikini top decorated with fringe, and bright red bottoms. Slater and Alec are wearing dark-colored swim trunks. Slater has his tongue sticking out, and Alec is making a playfully-shocked expression.

Ireland captioned the photo: "My boys," along with a few hearts.

According to The Daily Mail, the 17-year-old daughter of Alec and model Kim Basinger has previously spoken about how her father "approves" of Slater, which may be quite the compliment considering Alec's track record of angry outbursts in public.

Judging by the funny photo, the boys seem to be having fun on a day out in the Hamptons. In another picture, Ireland and her pregnant stepmother Hilaria Thomas are captured in a glamorous shot in the New York sunshine. The whole family is getting along nicely!

Ireland lives with her mother Kim in Los Angeles, but frequently visits with her father on the East Coast, The Daily Mail reports. She also travels often to Maui, Hawaii, to spend time with Slater.
