It's a family reunion on tonight's episode of ABC Family's BUNHEADS, as Broadway's Hunter Foster, real-life brother of series star Sutton Foster, guest stars as her on-screen sibling. In a recent interview with BroadwayWorld (check it out here!), Sutton spoke about the unique experience, "..we've never really acted with one another so it's been really cool. The other day I said, 'I don't think I've ever looked at you quite so much in my life!' So it has been like, 'Oh my God, I'm like acting with my brother!', so it's been really, really fun. It's been a really cool opportunity." Get a first look at the episode entitled 'The Astronaut and the Ballerina' below!
