Minnesota Timberwolves star Marko Jaric is over the moon about his relationship with Victoria's Secret model Adriana Lima. But don't believe rumors that he's shopping for engagement rings. At least, not yet.

The couple have been dating for the last six months, but Jaric says he was perplexed by a Web-based rumor about his checking out the local jewelry store for the big stone.

"I am not shopping right now," Jaric, 29, tells PEOPLE. "But I could start tomorrow. I am that close. I'm definitely not yet engaged, but it doesn't mean we're not thinking about it."

At that point, the entire process may come as a surprise. "I would rather keep that my own secret," says Jaric. "It's a life decision ... a private thing."

The stoic Serb admits he's not normally romantic, but being with the Brazilian supermodel, 26, has changed him. "I was not the person to fall in love easily. I am a difficult person from that standpoint," he says. "Now, it's a little different situation."
