Alessandra Ambrosio tweets a photo from Tulum, Mexico

Alessandra Ambrosio was called on to do more bikini duty for Victoria’s Secret over the weekend and missed the big costume parties in New York. She’s been globe trotting for the lingerie brand, and Tweeting along the way.

Most recently she was in Tulum, Mexico, a center of worship for the ancient Mayans. Today, it mainly draws sun worshipers. In fact, it’s known as the Mayan Rivera, plus it has fantastic Mayan ruins.

“Alright, I missed a great halloween party last night in ny, but I guess it was worth it!!!,” she Tweeted, along with a photo of herself on the sandy white beach.

Ambrosio flew down to Mexico Oct. 30 and is already back in New York City.

Before that, she jetted off to Toronto to celebrate the grand opening of Victoria’s Secret’s newest store in the Toronto Eaton Centre in Toronto, Ontario, Canada. Ambrosio, 29, was joined by Lily Aldridge, 24.

“Toronto… Here I come!!!! So excited to see the city and the new VS shop!!!” Ale tweeted.

Alessandra is also getting major face time in Japanese Vogue, where fashion director Anna Dello Russo, who styled Alessandra for the fall 2010 Moschino campaign, just can’t get enough of her.

But most of the attention is focused on the Brazilian model’s work with Victoria’s Secret’s new seven-way custom bra.

Wear it strapless, one strap, halter, classic, v-front, crisscross or crossback. Each cup size has unique shape and padding to feel custom-made just for you, according to the company.
