Jennifer Lopez, Ivanka Trump and Kim Kardashian among stars to post Father's Day tributes

Father's Day is for all dads — even those who are exes, step-parents or no longer with us.

Dozens of celebrities marked the occasion on Instagram, posting tributes to the great guys in and out of their lives. Jennifer Lopez created two separate photo galleries, one honoring ex-husband Marc Anthony and the other celebrating fiancé Alex Rodriguez. Some of the sweet photos even show Anthony and Rodriguez together, and fans were quick to praise the singer for showing respect to both men.

"Emme and Max love you soooo much!! Thank you for these two beautiful coconuts!!!" Lopez wrote to Anthony before penning a more extensive note to Rodriguez: "How lucky are we to have you in our lives. Not only do you make us all laugh everyday, you help us to be our best selves with a loving gentle hand."

Ivanka Trump shared a photo of her husband, Jared Kushner, walking the White House halls alongside President Donald Trump, calling them both "incredible dads."

Meanwhile, other stars took a moment to reflect on their late fathers. Kim Kardashian shared a photo of her teenage self with dad Robert Kardashian, who died due to esophagus cancer in 2003.

"You would be so proud of The Robert G Kardashian Esophageal Center at UCLA," Kardashian wrote. "I have seen how so far in such a short period of time that we have helped so many and I am grateful to all of the amazing staff and doctors!"

Demi Lovato thanked her stepdad, "the man that raised me as his own," for "showing me how a man should be there for his family."

"I couldn't have asked for a better father," she said.
