'I just need to take better care of myself,' she tells MTV News.

Selena Gomez seems to have made a full recovery from her recent hospitalization for food poisoning and exhaustion.

The young star has made several public appearances since the news broke, but it was on Thursday, when Gomez appeared on the "Kidd Kraddick in the Morning" radio show, that we learned what may have been the culprit behind her illness: junk food. "I do eat. The problem is, I don't eat right," Gomez said. "I love everything that's possibly not good for me."

On Friday (June 17), MTV News caught up with Gomez as she promoted her new flick "Monte Carlo," and while she assured us that she "feels much better," she's not completely ready to rid herself of unhealthy food just yet.

"Well, not ever again; I am still 18," Gomez said when asked if she would not be eating any more junk food. "But I just need to take better care of myself."

Yet, there is one food Gomez has decided to eliminate from her diet: Nutella.

"No more Nutella, Leighton," Gomez laughed to "Monte Carlo" co-star Leighton Meester. The two, who play stepsisters in the movie, spent two months overseas in France and Monte Carlo and seemed to have developed a strong liking for the hazelnut spread.

"I know, I'm to blame for that," Meester said of getting Gomez hooked. "On the whole movie, we had Nutella with everything — Nutella with fruit, Nutella with everything."

What were some of their favorite Nutella treats? "We had toast, Nutella and bananas every day on set," Gomez said.

"[We had it] like five times a day," Meester added.

"Monte Carlo" hits theaters July 1 and stars Gomez as a teenager vacationing in Paris, where she is mistaken for a British heiress. The movie also features Meester and "Glee" star Cory Monteith.

Next up for Gomez, she will be hitting the road next month for her first headlining summer tour alongside Allstar Weekend and newcomer Christina Grimmie.
