Big Sean's love for girlfriend Ariana Grande knows no bounds, and now fans can hear just how much he feels for her in his song "Stay Down." Seriously, he puts a quantitative amount on his affections!

"I got a million-dollar chick with a billion-dollar p---y/ Every time I come, I swear to God I feel rich," he raps in the song off of his album, Dark Sky Paradise.

Although some women might feel a little embarrassed about the NSFW lyrics, it looks like the "Bang Bang" crooner is totally supportive! Big Sean told Rolling Stone that his ladylove is more than OK with his music and lyrics because she just wants to support his career. (But no, he didn't ask her for permission).

"I don't have to run it by my girl, but she hears," he told the magazine. "I played her the whole album before it came out, so she heard everything."

He continued, "She's super-supportive. It's cool, because she was a fan of mine before anything. The first thing she said when she met me was, 'Yo, I love your music,' and she rapped my verse from 'Gang Bang' with Wiz Khalifa. She was just an actress on TV at the time. She's very open-minded. I'm proud of her."

Although his latest album just skyrocketed to No. 1, which means his phone has been ringing off the hook with congratulatory messages, he told the mag that his girlfriend, who is successful in her own right, continues to make him happier than the fame or A-list status ever could.

"Really, the way it affects my life is being happy, man," he gushed. "You can't measure success in anything but being happy, and she's one of the things that really makes me happy. I appreciate her, and that's it. I don't really pay attention to anything else."

The support system works both ways, with the rapper on hand to be Grande's date to this year's Grammys.  

"I'm just excited to be here," Grande told Ryan Seacrest while holding onto her beau. "I never expected to be nominated in my first couple years of doing this, so it's an honor and I'm very excited. But I'm super-nervous, though!"

"She's pretty calm. She's cool. She says she's nervous, but she handles it great, man," the 26-year-old rapper gushed about her.
