Racy Victoria Justice Photos Leak: "Hacking & Stealing Is Not Cool," Singer Tweets

"I will find out who stole my private property," adds 20-year-old Nickelodeon alum, who says someone swiped her phone

Victoria Justice is seeking, well, justice—at least of the cosmic variety.

"Hacking & stealing is NOT COOL. #RespectPeoplesPersonalProperty #Karma," the Victorious star tweeted today after several sorta-racy photos of her in a bathing suit were splashed online.

Justice, 20, also tweeted at the website that posted the four pictures: "@oceanup I would never post a picture of myself like that. I'm not taking this lightly & I will find out who stole my private property." (OceanUp.com then posted her response.)

And then, to her fans: "I see the trending topic! You guys are the best! So much love for u all :) xoxoxo"

The otherwise squeaky-clean Nickelodeon alum, who recently made an appearance with Ryan Seacrest at the grand opening of the media center his foundation built at Children's Hospital of Orange County, has her debut album coming out this year.
