Karlie Kloss has taken to social media to share her baby's name.
The supermodel and her husband Joshua Kushner welcomed their first child last month but kept all the details quiet.
However, Karlie took to Instagram over the weekend to announce that she had given birth to a boy and named him Levi Joseph.
"Levi Joseph. 3.11.21," she captioned a close-up of her son's hand.
Karlie didn't share any further details about her little one.
However, her post quickly generated over 270,000 likes and congratulatory comments from the Project Runway host's celebrity friends.
"Congratulations darling," wrote Priyanka Chopra, while Lily Aldridge posted, "Cutieeeeee (sic) I can't wait to meet him."
"Love the name Levi. Love babies in general," added Martha Stewart.
Adriana Lima, Tyra Banks, Lily Collins, Irina Shayk, and Ashley Graham also shared sweet messages.
After rumours began to circulate last year, Karlie confirmed her pregnancy in November with a sweet Instagram video in which she can be heard commenting, "Good morning. Hello baby (kiss)."
The 28-year-old captioned the video "good morning baby" alongside a black heart.
Karlie and businessman Joshua, 35, tied the knot in 2018 after dating for six years.
