Kelly Osbourne is living her best life on vacation, and she's giving "zero apologies"! The reality star is currently relaxing on a beach with her young son Sidney - who she shares with ex-fiancé Sid Wilson. 

The doting mom took to Instagram on July 9 to share a series of pictures from their trip so far, including some stunning snapshots of her posing on a boat out at sea.

In the pictures, Kelly looked stylish in a white figure-hugging corset style swimsuit, which she teamed with a wide-brimmed straw hat and statement sunglasses. Kelly's impressive tattoo collection was also visible, including her most recent piece of body art - a pair of her late father Ozzy Osbourne's iconic round glasses on her thigh. She recently got this done on July 1 in London, at the world's first rotating tattoo studio on The London Eye. 

Kelly and Sidney's vacation comes just after a difficult day in their family, as on July 4, Sharon Osbourne marked her first wedding anniversary since her husband's passing. 

Kelly wrote a heartfelt letter to her mom which she shared on social media, which read in part: "I often find myself imagining him looking down on you with that magical smile the one that held so much pride and so much love. 

"I know he would want you to see yourself through his eyes: resilient, compassionate, courageous, and endlessly loving. Every day since he left, you've had to learn how to carry both grief and hope in the same heart, and somehow, you've continued to do it with extraordinary grace." 

Reflecting on Sharon's past year, Kelly continued: "He would be so incredibly proud of the woman you are becoming. Not because you've forgotten him, but because you've found a way to keep living while carrying him with you. That takes a strength few people ever truly understand." 

Despite the emotional day, Kelly made sure that her mom had a reason to smile too, later sharing another post featuring pictures of them dressed up as clowns. 

She explained in the caption that her friend, Evgeny Lebedev, had thrown a summer clown themed party which helped to take Sharon's mind off the sad day. 

"It was the perfect night and made what could have been such a hard day for my mum one we will both never forget. I don’t think we have laughed like that in quite some time," she shared, adding that she was "forever grateful". 

Ozzy passed away suddenly at home on July 22, leaving behind his beloved wife and children. He died just weeks after performing at the "Back to the Beginning" farewell concert in his hometown of Birmingham on July 5.
