Robin Thicke: I don't know if I'd be alive without Paula

As far as appearances are concerned, Robin Thicke and Paula Patton are happy as clams.

The couple has weathered rumors of infidelity in recent weeks after a photo of Thicke posing with his hand on the rear of an unknown blonde circulated on the Web. Neither Thicke, who's been a magnet for controversy this summer, nor Patton have mentioned the image - or the accompanying rumors that Thicke hasn't been faithful.

But with all the affection the two couple showed one another at Thicke's album party for "Blurred Lines" in New York this week, they probably don't have to.

After all, they do rely on one another through life's peaks and valleys, as the star pair told Prestige Hong Kong magazine.

"I’ve been there for his down moments and he’s been there for mine. Life is full of peaks and valleys," Patton, 37, said. "Robin has always been a great person to remind me to celebrate now. Even when it looks like I’ve got a role but don’t know for sure, he’s like, 'Let’s celebrate!'"

To hear Thicke tell it, he owes a lot to his actress wife.

"I don’t know if I would still be alive in some ways if it wasn’t for Paula," the R&B singer said. "She’s been my rock, my muse, my inspiration and I love her. The whole way."

It's true that Patton piped up with support for her husband's risque music video, "Blurred Lines," which featured nearly nude models. But in spite of the criticism for the music video and the song's lyrics, Thicke's collaboration with Pharrell and T.I. quickly became the song of the summer.

The success of that track alone has impacted his lengthy career "in every single way," Thicke said.

"I’ve had three number-one songs on urban radio. I was doing well. I was doing OK," he told the magazine. "But the difference is when a million people a day watch your video and two hundred million people a week hear your song. One thing it’s done is give me the finances and the power to actually set up my own charity. You can’t get that much and not give most of it back."
