Nicole Kidman and Keith UrbanNicole Kidman and Keith UrbanOo-er, Nicole Kidman and Keith Urban have set off our PDA alarm.

These snaps have even got Dr Love de-misting his specs.

Because Nic and Keith have had a rather cosy, courtside cuddle at the Australian Open in Melbourne.

The pair were snapped exchanging the most intense of loving looks.

So much so we bet some folk in the crowd may have been watching them and not the tennis match.

And can you blame them?

There's nothing like a celeb couple in love to get one feeling gooey.

And with a bundle of baby joy on the way too, the Kurbans must be on cloud nine.

See Nicole Kidman and Keith Urban looking loved-up.
