Kim Kardashian rang in her 40th birthday on Wednesday (Oct. 21), and her family took to social media to share tributes to the reality TV icon on her big day.

"Been doing empty stadiums Happy 40th birthday!!! I love you so much," Kanye West captioned a photo of himself and his wife kissing in a stadium on Twitter -- a sweet nod to his epic 2013 proposal in San Francisco's AT&T Park, which included a hilariously misspelled message on the Jumbotron and an orchestra playing the rapper's own music.

Meanwhile, Kris Jenner wrote, "I love you so so much it’s impossible to even measure and I am so proud of all you do. You are my sweet, beautiful inside and out, @kimkardashian" alongside two family photos, while Khloe and Rob Kardashian both posted throwback pictures with their sister on Instagram.

For their part, Kourtney Kardashian, Kendall Jenner and Kylie Jenner all rounded out the crew by sharing a plethora of Instagram Stories in honor of Kim, with the eldest Kardashian even sharing a peek at the beauty mogul's glam birthday bash featuring a performance by all four of her sisters. (The moment appears to have been filmed early for the current and final season of Keeping Up with the Kardashians.)

Kim herself also shared a heart-melting video of her second-youngest child with West, Chicago, sweetly singing "Happy Birthday" to her on her Instagram Stories during the day.
