Paula Patton reportedly doesn't approve of Robin Thicke's relationship with girlfriend April Love Geary who is much closer to the age of his son than him.

Robin Thicke is 38 years old while April Love Geary is 20 years old. The "Blurred Lines" singer's son with Paula Patton, meanwhile, turned five last April 7.

"The 20-year-old enjoyed the company of the R&B crooner as they blocked the aisle to smooch while at LAX recently, an insider tells OKMagazine.com exclusively," said OK! magazine. "And not only did they block the aisle, but they also delayed the boarding process!"

Robin Thicke and girlfriend April Love Geary were first linked late last year after the "Blurred Lines" singer and Paula Patton filed for divorce in October over his alleged cheating ways. The young model repeatedly said back then that they are just friends.

"What does Paula think of their relationship? A source says she 'thinks he's lost his mind.' Especially considering just months ago 'Robin begged Paula to take him back.' Who can forget his last album, which was aptly called "Paula," and was a huge flop?" said OK!

Early this month, Robin Thicke and girlfriend April Love Geary took along his son as they vacationed in St. Barts.

"The 38-year-old singer was seen splashing around in St Barts with the 20-year-old model - who showed off her toned figure in two different bikinis - and his little boy, aged five," Daily Mail said.

The "Blurred Lines" singer's divorce from Paula Patton was finalized last month as the former couple agreed on custody rights to Julian as well as the division of property.

"The terms of the settlement are private. There's an indication from the legal docs Paula is getting primary custody, but it's not spelled out specifically. They've also agreed on the terms of spousal and child support," said TMZ.
