Nicole Scherzinger has written a song for her racing driver boyfriend Lewis Hamilton.

Nicole has recorded 'I think I'm in Love' for the Formula One ace, but is unsure whether to include it on the new Pussycat Dolls record or save it for her next solo album.

Describing the track, Nicole said: "It is a very personal song. It's very in-depth and emotional - a real song that I know is going to connect with people."

The song may possibly feature on the Pussycat Dolls' second album 'Doll Domination' - which is to be released next month.

A source told Britain's The Sun newspaper: "She has only just finished it, but it could be rushed onto the new album. There are reports on the internet claiming to have the tracklist, but so far only about seven songs are definite. Nicole is really proud of this one and they could squeeze it on."

Dating 'Don't Cha' singer Nicole has also inspired Lewis to pick up his guitar.

Earlier this week, it was revealed Lewis has composed a song for her.

Nicole said: "He wrote a song for me and played it on the guitar."

Lewis and Nicole met at the MTV awards in Munich, Germany, last November and started properly dating in May this year.

'Doll Domination' will be released on September 23.

Its rumoured tracklisting is:

When I Grow Up

Bottle Pop

Away

Psycho

Fly the World

In Person

I Hate This Part

Whatever Happens

Barely Breathe

If I Were a Man

Love Gun

Take Over the World

Elevator

Watchamacallit
