Robin Thicke shares sweet pic with girlfriend April Love Geary and son Julian after settling custody battle


Robin Thicke is having some fun in the sun with his pregnant girlfriend, April Love Geary, and his 7-year-old son, Julian.

The "Blurred Lines" singer took to Instagram on Saturday to share a cute photo of the smiling trio sitting on a beach together in Hawaii.

Thicke, 40, captioned the sunny snapshot simply, "Happy Days."

Geary -- who announced last week that she and Thicke are expecting their first child -- rocked a royal blue two-piece that just hinted at her burgeoning baby bump.

The expectant mom shared the same photo, as well as a sweet pic of her and Thicke side-by-side which she captioned, "Love you."

Love you 🌞

Before hanging out on the beach together, Thicke shared several other pictures from their family vacation to the Aloha State, including a video of his son's wildly excited reaction to riding in a helicopter for the first time, and a photo of the crystal clear waters and sandy beaches that the singer snapped from the sky.

The cute family pics come just days after news broke that Thicke and his ex, Paula Patton, reached a custody agreement for Julian.

Court documents obtained by ET explain that Julian will split time between his parents. Thicke will have custody Monday through Wednesday and Patton will have custody Wednesday through Friday, with the two alternating weekends. They have also agreed to share expenses, including private school, and have worked out vacation and holiday schedules.
