R&B singer Robin Thicke and wife Paula Patton have had no shame about publicizing their affection for each other lately.

For fans of the soul singer and and actress, it could be hard to believe that showing their love as an interracial couple hasn’t always been so easy.

In a radio interview with Howard Stern, Thicke revealed that he was his wife’s “secret’ when they were dating in high school. He even admitted that Patton, an African-American woman, did not take her future-husband to her prom because she was concerned about the reactions they would get as a couple.

“The funny thing is, in high school she didn’t take me to prom, her prom, because she didn’t want everyone to know she was with a white guy because she was president of the Black Student Union,” said Thicke. “I was a secret. She didn’t want to show up with a white guy. Funny right?”

The couple, who have been married since 2005 and dating since they were teens, now have no problem cozying up for the cameras or talking about their marriage.

In the midst of the controversy that has surrounded the singer’s new song “Blurred Lines”, Patton defended her husband’s music by saying that she loved the racy song. She told E!’s Chelsea Handler that she inspired Thicke’s steamy video concept, and wanted to “jump his bones” after hearing it.

Thicke said during his interview with Stearn that a lot has changed in the 20 years since he began dating Patton, and they might have the entertainment industry to thank.

“I think that times are changing. The new generation doesn’t feel the same way as the last generation,” Thicke said. “It’s mostly the older people who have those thoughts.”
