Are Olivia Wilde and Harry Styles expecting? Fans are crossing their fingers that the duo are taking things in a new direction after the Booksmart director, 38, was spotted out and about in London sporting what looked like a baby bump. "Word is that Olivia may be pregnant," a source tells Star. "She's not confirming it just yet, but the rumor going around is that she's a few months along and looking at her tummy, it's hard to argue otherwise."
