Lottie Tomlinson has revealed she is expecting a baby boy with with her partner Lewis Burton.

The make-up artist, 23, took to Instagram on Sunday to share a cute gender reveal clip in which she and Lewis, 29, let off a cannon of blue confetti and powder.

Social media star Lottie, whose brother is One Direction singer Louis Tomlinson, held her hands up to her face in excitement as the cannon went off, before she turned and hugged Lewis.

The pair shared a kiss as the confetti and powder settled in the room before the short video ended.

Lottie captioned her post: ‘Our little baby.’

Her friends were quick to leave congratulatory messages in the comments section of her post, with former The Only Way Is Essex star Mario Falcone, writing: ‘Congratulations,’ along with three blue heart emojis.

Wayne Lineker, wrote: ‘Congratulations guys …amazing.’

Lottie took to Instagram last week to share a pair of snaps unveiling her growing bump as she announced she was expecting.

In the photos, Lottie sported a white crop top and a matching robe, as she posed with her hands cupping her bump.  

The second image showed Lewis gently cradling her tummy while gazing at the mother-to-be.

Lottie captioned the post: ‘just the 3 of us.’  

Businesswoman Lottie and former tennis player Lewis were revealed to be seeing each other in July 2020.

The pair are said to have bonded over the grief of losing their respective loved ones.

She sadly lost her mother and sister in recent years and Lewis lost Caroline Flack in February 2020.

Lottie’s sister Félicité, 18, died after an accidental drug overdose, three years after the death of her mother Johannah, who died of cancer.  

It’s understood Lottie became better acquainted with Lewis at a house party in May 2020 hosted by Caroline’s close friend Lou Teasdale, 36, which was held to mark three months since her tragic passing.

In late July that year, a source exclusively told MailOnline: ‘Lewis and Lottie have grown close after spending time together at a party at Lou’s house.

‘They have been meeting up in secret for weeks but their newfound friendship hasn’t gone unnoticed by mutual pals.

‘Not all of Caroline’s friends are happy with how the situation appears to be developing but can understand that both Lottie and Lewis have been there for each other as a shoulder to cry on.’

Last December, Lottie spoke about wanting kids during an interview with PrettyLittleThing, revealing: ‘Yes I definitely want kids, I want five!’  

Lewis was previously in a relationship with the late presenter Caroline Flack, before she tragically died by suicide in February 2020.

Caroline passed away at her London home on February 15 of that year, days before she was due to face trial for assaulting Lewis, who she had been in a relationship with for just over six months.

The TV presenter was arrested in December for assault and charged with attacking the model at her home in Islington.

Lewis dropped his assault complaint against Caroline but prosecutors pursued it and the couple was told not to have any contact.

It was confirmed following the inquest that Caroline took her own life after hearing she would definitely be prosecuted for assaulting her boyfriend, a coroner ruled.
