The 30-year-old showed off his bleached locks, reminiscent of Chris Brown's blonde phase.
And despite hitting back at rumours of a romance with Rihanna, claiming they were just 'good friends', the F1 racing driver had a very Riri-esque eagle tattooed on his neck this month by her tattoo artist.
After the twosome were spotted partying in Barbados and New York, Hamilton - who split with Nicole Scherzinger in February - told E!:
"You know, I've known Ri for a long time.
"We've been friends for a while. We get to hang out every now and again..."
A source claiming to be close to Rihanna added at the time:
"Rihanna and Lewis had a nice little getaway last weekend in Barbados. Rihanna also spent time with her friends and family but Lewis was the only romantic interest on her mind.
"She is not at any point in her life now ready to settle just for anyone, but she is enjoying the time she has with her friends and also focusing on work."
Ooher!
