Boyzone star Ronan Keating splashed the cash to give his girlfriend Storm Uechtritz a birthday to remember.
The X Factor Australia judge organised a romantic cruise around Sydney Harbour with friends, as well as a slap-up dinner for her 34th birthday.
Guests at the glamorous bash included Ronan's fellow X Factor judge Dannii Minogue and her beau Adrian Newman.
The couple were snapped raising their champagne glasses in a toast to the good times as they mingled with friends.
Storm, a model and TV producer, stunned in an all-white outfit, including a sleeveless top with a sheer-floral pattern.
Ronan was dapper as usual, donning a light blue shirt and white trousers to match his partner's look.
And Storm - who posted pictures of the party online - admitted that it was "such a special night" and "so thoughtful" by her "baby".
"Everything was planned and selected by Ronan right down to the candles and hand soaps in bathrooms. So thoughtful. Such a special night - thank you baby," she said.
"Thank you so much everyone. Such a special night and so much fun," she added.
The couple have been together for around two years after meeting on the set of X Factor Australia where she used to work as a producer.
They hooked up a after Ronan's split from his wife Yvonne in 2012.
