After confirming their newfound romance only six weeks ago, the pair were photographed having an affectionate PDA on The Island floating bar on Sydney Harbour on Sunday.
Ronan, 35, and Australian TV producer Storm, 31, downed some drinks with Ronan's X Factor Australia judge pal Mel B and her husband Stephen Belafonte, who co-owns the floating bar (remember Kim Kardashian and Mel B's recent boat date?).
"Storm and I have been friends for some time and that has recently evolved into something more serious. We are both really happy," Ronan told The Sunday Telegraph last month.
Storm is rumoured to be moving to the UK with Ronan when the current season of The X Factor wraps up.
It's a promising new beginning for Ronan, whose affair with a backing dancer ended his marriage to ex-wife Yvonne last year. Ronan and Yvonne have three children together: Jack, 13, Missy, 11, and Ali, seven.
The Irish singer opened up to us recently about surviving the crazy life of a boy band, and his efforts to create an Australian One Direction on The X Factor watch below:
