Sister act: Auntie Kylie joins pregnant Dannii Minogue at stylish awards bash

In a matter of months Kylie Minogue will become an auntie again when her famous younger sister welcomes her first baby.

And her pride in mum-to-be Dannii was never more evident than when the gorgeous duo teamed up for a rare red carpet appearance together at a magazine awards ceremony.

Her arm placed protectively round her X Factor star sibling, who hid her burgeoning baby bump beneath a flowing yellow Lisa Ho gown, Kylie was on hand at the Elle Style Awards to present her sister with the best TV star award.

The Australia-born pair were quite clearly revelling in each other's company.

Speaking after the event, Kylie, 41, said it had been "wonderful" to be able to present the Australia's Got Talent star with her trophy, the pair both agreeing it had been a "family affair".

"There are few things we've got to share over the years," added Dannii. "And it's so lovely to be presented this (award) by my lovely sister."

Pregnancy is clearly agreeing with the glowing 38-year-old, who is expecting her first baby with model boyfriend Kris Smith in July.

But, while she was immaculately dressed at the event, the Marks and Spencer model admitted she has been having something of a clothing crisis of late.

Writing on her Twitter page ahead of the bash, Dannii tweeted: "tonight - what to wear...what to wear....?????", before revealing at the event: "I've just gone stage one with the wardrobe where no jeans fit."

"Can't get any of them on and you buy jeans with stretchy bits at the front. The rest, I don't even know how it works," she said.
