Weekend Today star Rebecca Maddern has proved that she's in the best shape of her life ahead of her 44th birthday by donning a figure-hugging neon yellow mini dress on Monday night.

The mum-of-one's frock added a welcome pop of colour to another high octane episode of Ninja Warrior, which she hosts alongside fellow Channel Nine presenters Shane Crawford and Ben Fordham.

The 'Cutout Long Sleeve Mini Dress' by designer Karen Millen was the perfect fit for Rebecca and featured a peekaboo opening below the collarbone as well as two more cut-outs over the shoulder blades.

Subtle metal detailing highlighted Rebecca's waist while the above-the-knee hemline kept the whole look fun and fresh.

Her followers on social media gave the eye-catching outfit the seal of approval, with many commenting on an Instagram photo she shared on her account.

"LOVE the dress. Which brand? I must have one," wrote a fan.

"Beautiful as always Bec," added another.

'Never felt better'

Rebecca recently opened up about how she feels about her body heading into her mid-40s in an interview with Body+Soul, saying that she's 'never felt better'.

"I know people say age is just a number, but it truly is," she told the publication. "Sure, I look in the mirror and think, oh gosh, I wish my boobs were a bit higher. But honestly, I've never felt better."

Bec went on to speak candidly about the 'very difficult time' she experienced in her late 30s while undergoing IVF in the hopes of having a baby.

She and her husband, Trent Miller, had all but given up hope on falling pregnant when Bec conceived naturally around her 40th birthday. Nine months later the couple welcomed their 'tiny miracle,' daughter Ruby, who is now three years old.

Bec admitted she didn't put pressure on herself to 'bounce back' after giving birth. "Even being on television, I just didn't let that factor into my recovery and my looking after my baby properly.

"The care factor almost reduces down to zero by the time you get to 40. That's such a freeing and liberating place to be."

Nowadays, Bec keeps fit by running three times a week and doing weight training at the gym.
