"I don't know how long they have been together and I have not met him yet, but I'm looking forward to it. We just found out about her pregnancy a couple of days ago," added the father.

"I think they met in New York socially because she works for Virgin Airways and often stops over in America," he went on. "The main thing is for them both to be happy and they are — they have just hit it off together."
