Smiling in her floor-length black dress, new mum Michelle Keegan looked forward to her first night out since giving birth to baby girl Palma.

The actress posed alongside husband Mark Wright at London’s five star Corinthia Hotel on Thursday night, as they prepared to make their way over the road to The Savoy. 

They were there to support the former TOWIE star’s sister Jess Wright’s charity event in aid of her son Presley, who was born with a life-threatening heart condition.

Michelle, 37, was also there to cheer on Mark who was hosting the night, the Have A Heart gala, to raise money for Brompton Fountain, which supports the treatment and care of seriously ill children at Royal Brompton and Harefield Hospitals, which has been credited with saving little Presley’s life.

He was diagnosed with congenital heart disease called ‘Bicuspid Aortic Valve when he was a tiny baby.

But Michelle decided to avoid the fanfare of the red carpet by slipping in the side entrance - perhaps to make sure the attention was on Jess rather than her. 

Instead Mark posted on Instagram, writing alongside a picture of the couple, who married in 2015: ‘Sharing the snap to Instagram, Mark penned: ‘Mum and Dad just got scrubbed up, ready for our 1st night out.’

Regardless, Mark and Michelle wanted to ensure that they looked the part so she got fully glammed up by getting ready at the Corinthia, after all, it had been several months since she enjoyed a night out on the town.

Meanwhile, Mark had to make a last minute dash the shops when he realised his white shirt was a little on the snug side.

A source said: ‘Mark and Michelle wanted to support Jess, it was so important to them and the rest of the Wright family.

‘Things have been difficult for Jess but she has received a lot of help and she wanted to give back by holding the event. 

'Mark and Michelle travelled to London and Michelle got ready while Mark had to rush out and save his own day with a new, slightly bigger shirt. He saw the funny side.’

They joined guests such as Denise Van Outen, Kimberley Walsh and Zoe Hardman, while Britain’s Got Talent winner Sydnie Christmas reduced guest to tears with a poignant rendition of Tomorrow. 

There was also an auction during which guests could bid for prizes such as BGT final tickets.

One guest told MailOnline: ‘Many of us were in tears as we heard some terribly sad stories about children affected by heart conditions.’

Last August Jess, 40, revealed that Presley has the disease, writing on Instagram that it was ‘something he was born with & happens to a small 1% of us.’

She added: ‘Essentially, instead of having three leaflets in his aortic valve, like most, he only has two.

‘This condition affects how blood flows from the heart to the rest of the body and will require monitoring & care over time.

‘I won’t go into the full details right now, but while this is please God not a fatal disease, we are coming to terms with the fact that our son will need intervention at least twice in his life.’
