The singer-turned-TV star ended her three-year romance with the former rugby player in April, but they have put the break-up behind them for the sake of their little boy, Ethan.
The tot turned two on Thursday and his proud mum hosted a party for him at her home in Melbourne, Australia on Saturday.
Smith was seen attending the bash along with other guests.
The news comes amid rumours the pair may be heading towards a reconciliation.
