Photographer Mario Testino unveiled his In Your Face exhibit at the Museum of Fine Arts in Boston last night. Gisele Bündchen stepped out for the event, showing off her growing baby bump in a Halston dress, which she covered up with a Tom Ford jacket. Gisele wasn't the only model on hand since a Versace-clad Alessandra Ambrosio made an appearance as well. She's since returned to NYC, where she's unveiling the $2.5 million Victoria's Secret Fantasy Bra. Alessandra appeared on Good Morning America today to chat about the diamond-encrusted lingerie after sharing that she'd been "waiting a long time" to model the luxury undergarment. She'll be wearing it in the brand's annual fashion show, which airs on Dec. 4.
