Robin Thicke and his girlfriend are "in love". The 'Blurred Lines' hitmaker - who split from former wife Paula Patton earlier this year - is getting serious with 21-year-old model April Geary. Sharing a picture of the pair on holiday in St. Barts on Instagram, she wrote: "Lucky to be in love with my best friend (sic)" Meanwhile, the 38-year-old singer previously revealed his family helped him move on from his split from Paula. He said: "I just finally took a few months off or more. I spent a lot of time with my parents even, talking with them and getting their advice. I always kind of grew up thinking I knew what I was doing. "When you have some tough times, you call on your parents, you call on your grandfather for advice, and I just spent so much time with my son and that just made me realise what's important." And whilst Robin has penned an album about Paula, he insists his recent track 'Back Together' isn't about their relationship. He said: "Actually I didn't write this song so I can't take credit for the meaning. I just heard this idea of getting back together and getting yourself back together, and what I was going through at the time I really really related to that and connected to it. "It's more about the theme of getting yourself back together with love and partnership."
