He was spotted by the pool of the Fasano yesterday with models Fernanda Motta, Alessandra Ambrósio, and Ana Beatriz Barros.

If he keeps on hanging out with Rodrigo Santoro and hooking up with every brunette in the country, I guess the answer is no. The pictures above with his latest victim were taken yesterday in the afternoon in Arpoador.

And on more celebs-who-obsessed-with-Rio news, Bruno Astuto at newspaper O Dia reports that Madonna is now looking to buy an apartment in the city (with water views of course).

Paris Hilton became the face of a Brazilian beer this Carnival, wore a completely see-through dress at a party, and twittered non-stop from the Sambadrome (in her Louboutins of course).

Sans Madonna, Jesus Luz answered interviews in English last night, and showed the world a brand new tattoo he got on his calf. He also spinned at a lounge at the Sambadrome and had his set cut short because of complaints that his set had nothing to do with Carnival.

Gerard Butler is probably the only person who enjoyed Carnival this year more than Madonna. He had breakfast shirtless at the Copacabana Palace, hung out with his buddy Rodrigo Santoro, and was rumored to hit on every Brazilian woman he passed by. Guess what happens in Rio stays in Rio.

I love the fact that Madonna seemed to be having a really good time in the middle of all the crowd last night at the Sambadrome.

More pictures and a video of Madonna's first Brazilian Carnival after the jump.
