Pregnant Kelly Osbourne showed off her blossoming baby bump as she appeared at her mum Sharon's Gatsby-themed 70th birthday bash.
The 37-year-old looked suitably styled for the event at the Osbourne's LA home for the Gatsby themed event wearing a purple maxi dress with a black headband and pearl necklace.
Her brother Jack was also photographed heading into the bash, looking suave in a white blazer.
Kelly, who is expecting a boy with boyfriend Sid Wilson, 45, told Entertainment Tonight that her dad Ozzy Osbourne, 73, was 'beyond excited' for the new arrival — their first grandson.
Kelly said: ''[Dad]'s told everyone before I ever got the chance to. But I will say, every single day he does this little song and this little dance about how excited he is.''
The “Crazy Train” crooner has four granddaughters: Pearl, Andy, Minnie and Maple.
The Osbourne's other offspring singer daughter Aimee and TV star son Jack Osbourne, also attended the event along with Sharon and Ozzy's grandchildren.
The former X Factor judge posted on Instagram : "All my wishes in one room. My [heart emoji] is full."
And in a poignant moment singer Kelly was on the mic to welcome her parent Sharon and Ozzy took to the dance floor for a slow dance to James Arthur's "Say You Won't Let Go."
Ozzy, who has been diagnosed with Parkinson's disease, gave up his cane to Kelly and his granddaughter so he could fully wrap his arms around Sharon.
But despite the Black Sabbath star spilling the beans Kelly still had nothing but praise from her parents for supporting her 'every step of the way' of her pregnancy.
The singer has been having a tough time after her ankles swelled and she gained weight in her third trimester before being diagnosed with gestational diabetes.
''At first I thought it was something that I had done,' Kelly told People. 'I got it in my third trimester and basically, I thought it was something that I had done wrong.'
''This whole pregnancy, I've had no cravings except for sugar. The number one thing for me that I realized was taking me down was sugary drinks and it was juice.''
Kelly managed to alleviate her symptoms by eliminating sugar and restricting carbohydrates.
According to the CDC, gestational diabetes affects only 2% to 10% of pregnancies and occurs when the body produces a lack of insulin while pregnant.
She added 'I'm not doing it for myself,' she said. ''I'm doing it for my baby.''
She attributed the worsening of her symptoms to an increased craving for sugar. This motivated Kelly to partner with the No Sugar Company and celebrate National No Sugar Day on October 3.
Kelly has also opened up about her parenting journey and explained she's decided not to breastfeed her baby due to continuing use of medication.
The singer said she'd faced backlash from friends saying she will "miss out on that bonding period" but Kelly - who has publicly battled alcoholism, drugs, depression and anxiety - feels it is more important to maintain her wellbeing for the whole family.
