One could make the joke that Robin Thicke took both of his kids to the beach on Tuesday. After all, son Julian is 5 and Robin's girlfriend April Love Geary is just 20 years old!

The 38-year-old singer and his lady love hit the beach in Malibu yesterday, and while she was busy soaking up the sun and chatting with strangers, Robin and Julian hit the waves -- or got hit by the waves, rather. Poor Julian got knocked over in the water, and after the incident Robin chatted briefly with a lifeguard to make sure Julian was OK.

After a dip in the Pacific Ocean, the trio headed to lunch, and April showed off her flawless figure in a simple white dress. She's been with Robin long enough that we can't call her a rebound, and while she's no Paula Patton, she's definitely a babe!
