The Formula One ace is committing his feelings to song in a rumoured attempt to win back the 'X Factor' judge, after they split earlier this month following five years together.
Posting a picture of himself in the studio on Instagram, he wrote: “My hideaway, pouring my heart into this track!!”
Lewis then revealed the song is called 'All Good Tonight', as he posted another snap of himself playing guitar.
His studio session followed an emotional outpouring from the sportsman on Twitter last week
“If you’ve found that special some-one, don’t EVER let them go no matter what!!" he tweeted. "Nothing in this world is more important.”
He earlier revealed that his split from Nicole had 'turned his world upside down' in a subdued interview with Sky Sports.
She didn't look to be faring much better either, as she hit the town with Miley Cyrus over the weekend.
The former Pussycat Doll was pictured looking pensive as she left a London club with the 'Hannah Montana' star.
Come on guys, work it out!
