The soccer star and model is famous for his various hairstyles and offered to style Lopez's hair into a faux-hawk on Lopez Tonight!
Beckham told the host he's no novice and often styles his own hair.
He said, "I kinda get bored... I wake up in the morning and I'm bored with what my hair looks like and I'll just cut it myself.
"My mum's a hairdresser, so I inherit that a little bit."
Beckham took the scissors to Lopez's hair and then gelled it into shape.
