HOLLYWOOD, Calif. — Robin Thicke and Paula Patton have one less worry with their first baby on the way - choosing a name!

"We like Julian if it's a boy and Isabella if it's a girl," Thicke tells People of the couple's choices.

With Patton due in May, Thicke also said he's prepared to be on call for several more months.

"I'm just trying to make her as comfortable as possible and hopefully nature will take care of the rest and give us a healthy baby," he said.

The high school sweethearts, who met at a teen club when Thicke was just 14, announced the pregnancy last month.

Thicke, 32, and Patton, 33, have been married since 2005.
