Pregnant Myleene Klass, 40, covers baby bump with 'Happy' jumper while out with ...

She kept off the radar for a while - unbeknownst to her fans that she was pregnant with her third child.

But since announcing the news on Valentine's Day, Myleene Klass has been proudly showing off her blossoming baby bump - her latest excursion seeing her step out with her eldest daughter, Ava, 11, on Monday. 

The glamorous pianist, 40, is expecting the child with her other half, Simon Motson - and looked fresh-faced as she walked alongside Ava, in casual ensemble.

She wore a pink baggy sweater, with the word 'Happy' emblazoned across the front, which she sported over a pair of black jogging bottoms and white trainers.

Looking typically smiley, Myleene added a chunky pair of black-rimmed glasses to the look, wearing her brunette locks up out of her face.

Ava looked to her mum for inspiration in a similarly casual ensemble - a black strap top, cargo pants and white sneakers.

She wore her locks loosely around her shoulders, braving the cold and drizzle by opting out of wearing a coat.

On Friday, she made her first public outing since announcing her happy news as she left her workplace at Global studios.

The expectant mum sauntered out of the London studios in her backless heeled boots, looking glowing. 

Myleene's first outing came the day after she broke the news she was expecting her third child - but her first with her PR guru boyfriend.    

The TV star and fashion PR went public with their relationship in May 2017 and between them share four children from previous relationships already.

The Instagram photo posted on Thursday afternoon shows the star posing in black lingerie with her hands lovingly resting on her sizable bump.

Myleene is a devoted mother to daughters Ava, 11, and Hero, seven, who she shares with her ex-husband Graham Quinn. 

They now happily make up a family with Myleene's boyfriend Simon and his brood, a son and daughter from his previous marriage. 

Her new love comes six years after her failed marriage with the father of her two daughters, Graham Quinn, 41.

The bodyguard walked out on her 34th birthday in April 2012 putting an end to their love, with their divorce finalised in 2013.

Discussing her devastation, she admitted to Woman magazine: 'I thought I'd never smile or trust anyone ever again'. 

But speaking earlier this month to Fabulous Magazine of her romance with Simon, she mused: 'How awful that I could have gone through my life and not met him. 

'Imagine never getting why people write those crazy love songs or do crazy things.'

‘I get it now as a grown-up, and it’s a lovely, lovely thing. To feel like this is a whole other level, and it’s quite incredible. I’m
