Kelly Osbourne shared a message on Instagram detailing her return to work.

She recently took on her first work since the birth of her son, Sidney.

Kelly said she had a newfound respect for working mothers.

She confessed that leaving him was difficult as she missed him.

The TV star, however, took her baby with her on her second day of work.

She made her mother, Sharon Osbourne, a grandma for the fifth time after welcoming Sidney.

Sharon announced the news and revealed her grandson's gender and name.

Unfortunately, the 38-year-old shared a message showing she disapproved of her mother's announcement.

She did not name anyone but wrote that she was not ready to share her son with the world.
