Robin Thicke loads bicycles into his car after riding around the beach with his older kids… while his fiancée April Love Geary stays home with baby Luca

His fiancée April Love Geary welcomed their third child in less than three years in December.

And Robin Thicke spent the day out in Malibu on Saturday as he took his oldest children out for a bike ride at Zuma Beach.

The 43-year-old singer–songwriter was spotted as he loaded up his families bicycles into her car before heading home.

Robin was dressed sportily in a simple black T-shirt with a pair of black Puma sweatpants.

He also rocked a set of navy New Balance trainers and blocked out the sun with a black Adidas baseball cap and sunglasses.

The Blurred Lines singer was riding with his oldest son Julian, 10, whom he shares with his ex-wife Paula Patton.

Julian wore a blue bike helmet for safety and covered up with a yellow sweatshirt, black Adidas track pants and red and blue sneakers.

While her husband was out getting some exercise with the older children, April stayed home to care for little Luca.

She shared a cute snap featuring the baby earlier in the week as she cradled him in her arms. 

Late in December, she admitted that she was ‘really tired’ after giving birth to three children in quick succession, though she said her kids ‘make it all worth it.’

April only announced that she was pregnant back in October with a photo of herself at the beach that revealed her already pronounced baby bump.

She and her musician husband met in 2014, after he had separated from Paula, and the two struck up a relationship. 

They got engaged on Christmas Eve 2018, while April was pregnant with their second child.
