Prince Harry went bowling on Friday night at the All Star Lanes to celebrate turning 27.
After spending his birthday on Thursday doing Apache helicopter training at RAF Wattisham airfield, Harry relaxed with friends and enjoyed a few beers and a burger in Bayswater.
'Harry didn't hire the private area - he just took a lane next to everyone else, happily posing for photographs when asked,' an onlooker tells the Daily Mail. 'He was dressed down in jeans and a linen shirt.
'He and his friends were very competitive.'
Harry's more often seen on nights out in posh clubs, but it seems he fancied something more low-key after a summer of partying.
He recently got in trouble with Kate Middleton's sister Pippa, 28, after he fell into a nightclub pool in Croatia.
'Pippa texted him to suggest that he starts acting "less like a teenage chav, more like a real man",' a source tells us.
