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.
