The blonde reality star took to Twitter this week after learning his boutique in Essex had been targeted on Sunday, 20 July.
Harry tweeted: "Disgusting people out there. People egged my shop last night. Jealousy gets you nowhere."
He added: "We have you on camera, you should have smiled."
Harry owns a boutique called Harry's World, on Ongar Road in Brentwood, which describes itself as the "blingest shop in Essex" on its official Facebook page.
Harry returned to TOWIE this season, after first finding fame in 2010 when the ITV2 reality show arrived on our screens.
He has been part of one of the biggest storylines of the season so far – his romance with co-star Bobby Cole Norris. They had been dating for around six months before the cameras were introduced to their lives, but sadly split for good earlier this month.
