WATCH: Patti Stanger Scolds Lonely 30-Year-Old

On last night's Watch What Happens Live, Andy Cohen put Millionaire Matchmaker star Patti Stanger to the test, asking her to offer dating advice to call-in viewers with a strict 45-second time limit. But 20 seconds was all Stanger needed to issue a harsh tongue-lashing to one woman who admitted she can't find love—because she's 30 years old and still lives with her parents.

Kelly from Yardley, Pennsylvania, rang up Stanger and laid out her problem: She lives at home and doesn't have a ton of money; how can she get over her insecurity about dating?

"Get out of the house! Why are you living at home?" Stanger exclaims. "You need to save money and move out right now, no man is going to date you if you live at home."

When Kelly asks tentatively, "So I need to move out?" Stanger goes on a rampage. "What is this, Princesses: Long Island?" she asks. "I moved out when I was 18! Where is this written where men and women can go home and live with their parents? How do you think you're going to get successful in life when you don't know how to do it yourself?"

Her final smackdown came when Kelly insisted she was "working on it." "Yeah, working on it, bulls---, get out of the house!" Stanger yelled.

Stanger, who's found her own bliss with boyfriend David Krause, had less severe advice for Christina, a 37-year-old caller from upstate New York who's divorced and wants to put herself back on the market. Stanger's directions were simple: "Get online! You need to date 'til you mate." Just be sure you don't Google your matches, Christina!
