Leo's still in love -- but he's not getting ready for a walk down the aisle.

Leonardo DiCaprio and model Bar Rafaeli are not engaged, a source close to the Inception star, 36, tells UsMagazine.com.

The couple sparked new marriage rumors last week when they arrived -- with DiCaprio's mom, Irmelin -- in Rafaeli's native Israel, where they met with her parents.

The source adds that it's "just a vacation."

According to AOL News, the paparazzi-plagued couple has been traveling in Israel with a convoy of armored cars and security guards. Before their Israel sojourn the couple -- celebrating DiCaprio's birthday -- hung out in Egypt and Jordan, joined by famous pals like Naomi Campbell and Kevin Connolly.

Often the subject of matrimony talk, DiCaprio (who once dated Gisele Bundchen) and Rafaeli, 25, have dated for nearly five years; they split for six months back in 2009.

"I am not thinking about getting married," Rafaeli has said. "I'm still young. And when I do get engaged, I might even hide the ring. I want it to remain private."

Her mom, former model Tzipi Levine, told AOL she approved of DiCaprio as a potential son-in-law.

"This is her choice. I'm happy for her when she's happy. Any man is lucky to be dating my daughter," she said.
