Channel Nine boss David Gyngell and his wife, TV host Leila McKinnon, have welcomed a new baby girl to their family.

The couple, who already have a son, were congratulated on Twitter by all and sundry on Wednesday.

The Today Show tweeted on Wednesday morning: "Congratulations to @leilamckinnon who has just had a little girl. All is well. Wishing you the best!"

A heavily pregnant Ms McKinnon tweeted on May 18 that she was feeling very uncomfortable.

"Is feeling so uncomfortable you want to give birth like having such a bad headache you're looking forward to the guillotine?"

Mr Gyngell was in the headlines earlier this month for his infamous punch-up with billionaire James Packer at Bondi Beach.
