Taylor Swift and Joe Alwyn have got problems, and friends aren’t sure they can solve them after he told the pushy pop star, 27, that he wasn’t ready to go public with their relationship. “Joe tried to play it off as though he just loves having Taylor all to himself, but he’s really worried about what would happen to his career if he came out of hiding,” confides a source close to the 26-year-old Brit. “Sure, being linked to Taylor has gotten him some good press, but he wants to be taken seriously as an actor. If things go south, he could become the biggest laughingstock in Hollywood.” Just ask Tom Hiddleston. And Calvin Harris. And Harry Styles.
