Steve Irwin’s niece, Rebecca Lobie, is pleading with her social media followers to stop being “bullies" on Instagram.

Lobie, 32, is the daughter of Frank Muscillo, who is married to Irwin’s sister, Joy.

Lobie said on Tuesday that she and her family have been inundated with "mean" messages after fans discovered her bikini-laden Instagram account last month, which is a stark contrast to the wholesome public image the Irwin family is known for, according to the Daily Mail.

According to the Daily Mail, in addition to her recent social media fame, Lobie also works as a restaurant manager and is married to car enthusiast Mick Lobie. They have two children.
