While the interview had been pre-taped before Justin and Selena's relationship reportedly hit the rocks, the Biebs told Oprah he has all he could ever ask for in his former Disney star girlfriend.

"I am all about really genuine people and I feel like she's one of the most genuine people," he beamed on Sunday's episode of Oprah's Next Chapter." She has a good heart and I can talk to her about anything."

When grilled about the couple's frequent moments of PDA caught by the paparazzi, Justin shrugged with a smile, admitting they can't help it; they're "always just touching each other."

In keeping with the topic of his favorite things, Oprah asked the teen sensation what he couldn't live without.

Ever the techie, Bieber said his laptop and iPhone were among his most cherished possessions. His favorite shows are Smallville and Friends, his preferred cereals are Crunch Berries and frosted Mini-Wheats, and (Selena aside) his biggest girl crush remains fellow superstar Beyonce.
