Robert Pattinson, 28, doesn’t mind introducing his new girlfriend FKA Twigs – whose real name is Tahliah Barnett – to his ex, Kristen Stewart, at some point. A source said: ”Rob and Kristen are inevitably going to cross paths. Tahliah is a huge part of his life and will be living with him when they are in LA. Rob has no problem at all introducing them to each other.” It’s believed Robert and Tahliah may bump into Kristen when he takes the British-born beauty to some of the favored spots in Los Angeles he used to visit with his 24-year-old former Twilight co-star, whom he split from when she cheated on him after they’d been together for four years. While they have only been dating for a number of months, Robert is said to be ”falling in love” with Tahliah. A source recently said: ”They’re very serious, Rob’s only seeing her, he’s not dating anyone else or even looking at other girls. He’s really happy, they’re falling in love, he’s totally wrapped up in her.”
