Lottie Tomlinson has named her newborn son Lucky.
The 23-year-old make-up artist - who is the brother of former One Direction singer Louis Tomlinson - and former pro tennis player Lewis Burton welcomed their first child together into the world last week, and the star took to Instagram to share a clip of her baby boy.
She wrote in the caption: "our perfect creation [heart emoji] introducing our son, our world, love of our lives [heart emoji] Lucky Burton."
Lottie also shared a picture on her Instagram Stories of herself embracing Lucky.
She wrote: "my boy [heart emoji] Lucky Burton"
And she posted a snap of Lucky lying on Lewis' chest, and wrote: "best daddy [heart emoji]"
Several stars congratulated the couple on their newborn, including Lottie's sister Daisy Tomlinson.
She commented: "i’ll love you forever Lucky"
Reality stars Ferne McCann and Lauren Pope also praised the pair on their new arrival.
Ferne wrote: "Ahhhhh congrats"
Lauren posted: "Aw congratulations, such a little beauty (sic)"
Last week, Lottie took to her Instagram Stories to reveal she had given birth.
She added the caption: "dreams do come true [love heart emoji]"
Lewis re-posted the message and had earlier shared a picture of Lottie, writing on his Stories: "Very proud of you, we are both lucky to have you [baby emoji]"
Lottie's sister Phoebe Tomlinson shared a picture of her pregnant sibling, and confirmed her newborn is a boy.
She wrote: "i am beyond proud of you. He is perfect. Love you both @lottietomlinson @mrlewisburton (sic)"
In February, Lottie and Lewis announced the news they were expecting a baby together.
Lottie shared an image of her growing bump as Lewis cradled her stomach, and she captioned the post: "Just the 3 of us."
Commenting on the post, Lewis wrote: "I love you both forever."
Lewis started dating Lottie in July 2020 and their romance was soon confirmed when they were seen holidaying together in Ibiza.
