Hey, that’s what siblings are for. All that Jack Osbourne tried to do was share a serious photo of himself and promote work he recently did. However, his big sister Kelly Osbourne couldn’t help but to poke fun at him.

Jack, 33, took to Instagram on Thursday, October 17, to post a snap of himself sitting on a fancy leather chair in order to remind people of his work on Travel Channel’s spooky show, Portals to Hell.  Kelly, 34, had other ideas though as she quickly responded in the comments section.

“You look like you are holding in [a] fart,” the fashion designer wrote.

People of course were loving Kelly’s little dig, as they quickly responded. “That cracked me right up,” one person said. Another added,”You guys are adorable! Such typical brother and sister banter!” While one fan chimed in with, “I love this! Makes me miss my brother even more.”

The siblings also have another sister, Aimee, 36. The trio’s parents are of course Ozzy and Sharon Osbourne. The bunch is obviously very close with one another. In fact, Kelly was by her mom’s side when she underwent a facelift procedure. “Kelly was with me for most of the time and when I woke up, she told me that I was going, ‘Help me, help me!’ And she’s like, ‘What can I do for you?’” The Talk cohost recalled during a recent appearance on Jimmy Kimmel Live!. “I’m like, ‘Just help me’ … I don’t know what I wanted help for!”

While the famous family may not find themselves under the same roof often, that wasn’t the case recently when Kelly and Jack took some time to give their mother a birthday surprise on an episode of her CBS daytime talk show  — they even brought along two of their mom’s granddaughters.

“We love you,” Jack said during the live appearance. “Happy birthday, I know it’s been a tough year, but onward and upward!” Kelly also chimed in with her own words, saying, “I love you so much, mom, and I hope you have the best day ever and thank you for everything that you do for us!”

The family may poke fun at each other sometimes, but it’s clear there is so much love here!
