The 31-year-old TV presenter was so devastated by the mass shooting in which 49 people were killed and 50 injured by a gunman at gay nightclub Pulse on Saturday (11.06.16), that she decided to get a tattoo on the side of her skull to show support.

She posted a picture of the inking on Instagram and wrote: "Solidarity: 'Noun. Unity of feeling of individuals with a common interest or purpose.' Individually, we have rights and unique gifts. Together, we have strength and powerful harmony. I have wanted to get this tattoo for a long time.

"The tragedy in Orlando devastated me and reminded me that every moment of our lives is precious. Every human is precious. Love hard. Live gracefully, authentically and with conviction, respect, purpose and compassion. Together we achieve what is impossible to those who stand alone. Those of us who embrace and respect freedom stand together, progress together, celebrate together and grieve together. You are not alone (sic)."

Kelly is not the only celebrity to publicly declare her support for the victims, with Lady Gaga joining thousands of people outside City Hall in downtown Los Angeles earlier this week where she helped to read out the names of those who died.

She said: "As we have now witnessed the largest mass shooting in American history, I can't help but feel that this level of hatred, like all prejudicial crimes, this is an attack on humanity itself."

Nick Jonas and Tituss Burgess were among those who gathered at a vigil in New York while Mara Wilson took to social media to reveal her sexuality as "bi/queer" in the wake of the mass killings.

Madonna called for an end to "hate crimes" and declared her support for the victims, posting an image of two men touching tongues on her Twitter account.

Underneath the picture, she wrote: "Love is love. Stop hate crimes. Any form of terrorism is a form of Hate! (sic)"

And Kim Kardashian West made an impassioned plea for better gun control laws.

Kim said the current legislation "makes it easy for dangerous people" to obtain weapons.

She tweeted: "I'm truly at a loss for words. To everyone in Orlando affected by this massacre, my thoughts, love, & prayers are with u.

"Under current federal law people on terror watch lists can legally buy guns -- this is called the Terror Gap.

"We have repeatedly called on Congress to close this loophole that makes it easy for dangerous people to get guns & kill. Nothing has changed!!!! People continue to senselessly die. When will these gun laws be changed?! (sic)"
