Memphis Depay: Date Night w/ Steve Harvey's Step-Daughter ... In $350,000 Whip

Manchester United soccer stud Memphis Depay took his famous girlfriend out in style the other night -- picking up Steve Harvey's step-daughter in a $350,000 Rolls Royce!!

The two hit up a Chinese restaurant in Manchester -- and even the parking ticket waiting on the whip couldn't ruin their evening ... probably 'cause the dude reportedly makes $125k per week.

As we previously reported, Lori Harvey and Memphis went public with their relationship last month.
