Kim Porter discovered the advantages of being Diddy's occasional girlfriend this week.
The music mogul invited 30 guests - including Grey's Anatomy actress Ellen Pompeo, co-star Sara Ramirez and Pompeo's husband Chris Ivery - to Murano Restaurant & Lounge to celebrate Porter's 38th birthday.
"The group serenaded Kim to Stevie Wonder's "Happy Birthday," and then they presented her with a cake," a source told People Magazine.
As you might expect, Diddy did everything in style: guests drank a specialty lemon drop martini made with Ciroc vodka. Executive Chef Luciano Sautto served a four-course meal to the mother of his three kids and her pals. And the ghost of Denny even showed up for a toast.
Just kidding, Grey's Anatomy fans.
We don't know if Kim Porter and Diddy are dating this week. But they are attending partie together.
