It's been two weeks since Miley Cyrus sent her last Twitter. And, sorry online universe, she isn't in Twitter withdrawal.
"I really haven't missed it," the singer, 16, said on 104.7 FM's Johnjay and Rich Show in Arizona Tuesday. "I thought I was going to miss it a lot more than I do, but I haven't even really looked at other people's, which is really weird. I don't really miss it. It's kind of odd."
On Oct. 8, she deleted her Twitter page after posting a message that seemed to be about Australian actor Liam Hemsworth, her "The Last Song" costar and rumored love interest.
"FYI Liam doesn't have a Twitter and he wants ME to delete mine with good reason," she tweeted.
She said on the Johnjay and Rich Show that tweeting also was costing her sleep.
"It was 3:30 or 4 in the morning. I couldn't sleep. [I thought], 'Maybe I could sleep if I wasn't so friggin' busy tweeting about not being able to sleep,'" she said.
Cyrus recently filmed a scene for "Sex and the City 2." In the scene, shot in NYC Oct. 16, she wore the same Matthew Williamson dress as Samantha (Kim Cattrall) to Smith Jerrod's movie premiere.
