Rooney - who is only 25 - has seen his hairline recede quicker than Michael Owen's international career. And the hot-tempered striker struggled to keep his shiny head in check when Owen, 31, poked fun at the profile picture on Rooney's Twitter page.
In a tweet which could be read by Rooney's 440,000 followers, Owen said: "By the way, how old are you in that photo? Your face looks like a 12-year-old's but your hair looks like a 60-year-old's!"
Rooney replied: "easy mo u know that's a sensitive subject."
Injury-prone Owen, who may have troublesome hamstrings but at least has a full head of hair, said: "Won't mention it again in public then!!!"
Rooney replied: "Good lad."
