Lew's that guy, Nicole?

The former Pussycat Doll, 33, paid her man a visit as he practised ahead of Sunday's Melbourne Grand Prix and brought along legendary womaniser Lenny Kravitz.

The trio chatted and laughed between Lew's sessions on the track, but the Brit must have been sweating about Lenny's reputation as a Casanova.

According to rock legend, the single strummer has successfully seduced the likes of Madonna, Kylie Minogue, Adriana Lima and Nicole Kidman.

Former X Factor USA judge Nicole and Lewis revved up their relationship again in February, four months after they split.

They blamed their busy schedules for the break-up, but have been inseparable since reuniting at one of Nic's gigs in Dublin, Ireland, in February.
