Kevin Federline appears on 'The Ellen DeGeneres Show'. USA - 06.09.06

The host presented a beaming Federline with a mini chopper and sidecar for his son SEAN PRESTON and unborn baby, expected next month (OCT06), when he appeared on DeGeneres' show.

DeGeneres also handed Federline a little leather jacket and baby biker sunglasses for his son and a pink outfit for his new baby, with 'Lil' Fed' printed on the back.

She then quizzed the dancer-turned-rapper about the sex of the unborn baby, asking, "Is it a girl? Come on... We're just guessing it's a girl."

Polite Federline replied, "We don't know what it is. I swear. I wish I knew."

Federline, who performed new single LOSE CONTROL on the show, has been telling reporters that his second child with Spears - his fourth in total - is due on Halloween (31OCT06).
