Cousins, fast friends, co-conspirators: Ireland and Hailey Baldwin appear to be all three, judging by their antics in recent days.

The daughters of actors Alec Baldwin and Stephen Baldwin have been palling around together in New York, flooding Twitter with Vine videos (many of them featuring Hailey’s older sister Alaia) and spending some quality time with Alec and his pregnant wife Hilaria.

An Instagram photo of the family and their puppies shows Ireland, 17, hugging her dad, framed by Hailey, 16, and Hilaria.

But the girls are just as likely to be found goofing around.

Hailey Baldwin just showed up at my hair appointment ugh can’t stand that troll,” Ireland jokingly wrote Wednesday on Twitter.

“Broke my hip, rib and collar bone tryna get a good vine,” Hailey added, just as facetiously.
