Brad Pitt and Angelina Jolie are reportedly set to go public with their romance in a TV interview. The Hollywood couple have so far remained tight-lipped about their relationship, which started shortly after Brad's split from ex-wife Jennifer Aniston. However, sources claim the 'Mr and Mrs Smith' co-stars will finally confess they are dating to famed US TV interviewer Barbara Walters. An insider is quoted by Britain's The People newspaper as saying: "Brad and Angelina had not gone public as he wanted to get his divorce out of the way and not hurt ex-wife Jennifer's feelings. "But most people realise what's going on and they want the public to know they're serious." Meanwhile, Brad has been spotted playing 'Dad' to Angelina's adopted children, Maddox and Zahara, while she is filming in New York. According to America's New York Post newspaper, the handsome actor carried baby Zahara in one arm, while holding hands with four-year-old Maddox with the other. Brad, who is said to be renting a house in the Hamptons to be near Angelina while she makes new movie 'The Good Shepherd', even had a bottle of baby milk sticking out of his back pocket.
