The baby bumps were on parade at the Metropolitan Opera 2009-10 season opening night in New York City tonight (September 21).

While pregnancy supermodel Karolina Kurkova flaunted her burgeoning belly in a drarpe grey number, expectant actress Leelee Sobieski showed off her bun in the oven in a sexy red number with not much else on underneath.

Proving that the rich and famous are living life recession-free, top tickets for the opening gala performance of Giacomo Puccini’s Tosca went for a mere $1250. For those who could not afford seats, the play was also transmitted onto multiple screens in Times Square and to a large screen at Lincoln Center’s Josie Robertson Plaza.

The gorgeous mums-to-be were joined by a bevy of A-list theatergoers, including the likes of Edward Norton, Joy Bryant, Martha Stewart, Mischa Barton and fashion designers Jason Wu and Zac Posen.
