"Happy Father's Day to the most perfect man Luna and I could ever ask for," she wrote on Instagram. "Since the day she was born, you've done every bottle with me, woken up with me to keep me company through every night. You don't mind diapers, get all the best burps, and read her Goodnight Moon like poetry. It makes me so happy to see so much of you in her smile and eyes that completely glow when looking at you. She will never look at anyone - anyone - the way she looks at you."
Gisele Bündchen celebrated her husband, New England Patriots quarterback Tom Brady, with an Instagram photo showing the family of four building a sandcastle on the beach.
"Happy Father's Day!!! We love you!!!," she wrote. The two share son Benjamin, 6, and Vivian, 3, while Brady also has an 8-year-old son, John, from a previous relationship.
Pink also took to Instagram to share two adorable photos, one for her father and the other of her husband, Carey Hart.
"Daddy Sir. Happy Father’s Day," she captioned a pic with her dad. "You were and always will be my first love. You taught me what love feels like, what it should be. What it meant to be strong but still allow others to hold you when you need it. You taught me what it felt like to be the most important thing in a person’s life. You gave my brother and I every part of you and every second of your day. The good, the real, the honest. You taught us how to navigate every water. You broke your back to Father us. Not a day went by that we didn’t feel important. Congratulations on a job well done. And THANK YOU for making my bar so high. I love you more."
The 36-year-old singer then posted a photo of Hart, 40, with their 5-year-old daughter, Willow. "And to you, my love. Carey Hart, you are a miracle," she wrote. "You are the most loving, patient, hands on Papa who came from a pile of rubble and ash with your own family, and who has become the most wonderful father my eyes have seen since my own. Willow will know one day how she hit the jackpot with you, and because of your love, she will be strong, and she will choose wisely. My eyes sometimes can’t believe how good you are. Happy Father’s Day to one of the best that ever did it."
Kendall and Kylie Jenner were among those who shared childhood pics.
"Happy father's day to this incredible soul," Kylie wrote on Instagram, while Kendall shared her own throwback with Caitlyn Jenner, captioning it with a simple heart emoji.
