Leonardo Dicaprio switches out Victoria's Secret models the way most of us lowly peasants switch out socks. (You guys do that once every few weeks, right?)

Well, it's about that time, so he's now hooked up with German bombshell Toni Garrn.

Leo was spotted coming back from the Monaco Formula One Grand Prix in France with the Victoria's Secret model, and nobody bat an eyelid because at this point it would be strange if he wasn't accompanied by one.

The 'Great Gatsby' star, 37, and his new love, 20, then boarded a yacht with an entourage -- possibly in a bid to reenact scenes from 'The Beach,' which came out when Toni was 8 years old. That's not icky at all!

“They’ve been getting quite close over the last week. There is definitely chemistry there,” a source told the NY Daily News. (We'll give it five weeks. Six, tops.)

Toni joins the ranks of several of her catwalk colleagues like Gisele Bundchen, Bar Refaeli and Erin Heatherton, who've all had a share of Leo love -- but it might create some bad blood between her and Heatherton, who allegedly wanted to settle down with the actor.

So it would seem Toni's safe for now, so long as her Vickie's secret isn't that she wants some kids and a house with a picket fence.
