Nikki Reed and Jenna Dewan are shocked by Johnny Lewis' death.

The former boyfriend of Katy Perry is believed to have killed himself on Wednesday (27.09.12) by leaping off his home after beating his 81-year-old landlady to death and the actresses, who both knew him, have spoken out about their sadness.

Nikki told E! News: ''It's horrible and shocking news. He was the nicest guy.''

''I never thought anything but great things about him. I have nothing to say except that he was a really nice guy. It's just crazy.''

Jenna added: ''It's so sad. It's a sad example of what happens if you lose your way in this town.''

A spokesperson for the Los Angeles Police Department said: ''It's a terrible tragedy as far as we're concerned and we're digging into the bottom of it.

''He appeared to have died from some type of fall, either from the stairway, or from the balcony, or from one of the roofs.

''The best we're piecing together now is that it appears that some type of altercation occurred inside of the house resulting in the death of the woman.''
