"Already so in love with you," April captioned a pic of her cradling her growing belly in a barely-there black bikini.
The 22-year-old model announced her pregnancy on Instagram in August. “Robin and I are very excited to share with you all that we’re having a baby!" she wrote. "The due date is March 1st, Robin’s late father Alan’s birthday!”
The happy couple has been spotted out together on romantic date nights.
The super-fit model's baby bump only just recently started to show.
In August, Robin ended a long custody battle over his 7-year-old son, Julian, with his ex Paula Patton. The actress was previously granted a restraining order against Robin, accusing him of child and domestic abuse. Now, the two will reportedly share custody of Julian.
