Hey Jay-Z, a word of advice -- don't leave a lady like Beyoncé Knowles out in the cold.

While the Jiggaman partied it up inside Area for an American Music Awards after-party, his bootylicious babe stayed in the car like a puppy patiently waiting for its owner.

After leaving Beyoncé sitting with her driver for at least 40 minutes, Jay finally emerged from the club to join his Naughty Girl in the couple's silver Mercedes.

With Beyoncé's latest single touting the lyrics, "I can have another you in a minute," Jay-Z better start being a little more attentive before he's left out in the cold.
