IT'S a good time to be a Young Diva, with two of the all-girl group's members throwing 21st-birthday bashes in consecutive weeks.

Last year's Australian Idol winner, Kate De Araugo, turned 21 yesterday and is hosting a big party in her home town of Bendigo this weekend.

Her groupmates and a host of celebs are on the invite list.

Ricki-Lee Coulter's birthday was a few weeks ago, but she celebrated with a party at her Gold Coast home on Saturday.

Guests included Coulter's former Idol mate Dan O'Connor, who left Derby Day early to fly north.

God, they're still so young!!
