Lewis Hamilton Crashes $2 MILLION CAR ... Blames 'Heavy Partying'

Formula 1 racing champ Lewis Hamilton has an unreal excuse for why he crashed his $2 MILLION Pagani Zonda supercar in Monaco this week -- he'd been PARTYING WAY TOO HARD!!!

Hamilton was reportedly driving through the streets of Monte Carlo early Tuesday morning when he lost control and hit a parked car around 3:30 AM.

According to the BBC, Hamilton had one hell of an honest excuse for the wreck -- "It was a result of heavy partying and not much rest for 10 days. I am a bit run down. I have been non-stop and trying to fit training in at the same time and not getting a lot of sleep."

Cops responded to the scene and Hamilton was given a breathalyzer -- but reportedly passed.

Hamilton later went to Instagram to issue a statement confirming the crash and adding, "Nobody was hurt, which is the most important thing."

"But the car was obviously damaged and I made very light contact with a stationary vehicle. Talking with the team and my doctor, we decided together that it was best for me to rest at home."
