Marc Anthony's Star-Studded 40th Birthday Bash

If you were impressed with the stars that came out to support Jennifer Lopez as she competed in the Nautica Malibu Triathlon this past Sunday morning, get a load of the ones that stepped out to party with her husband Marc Anthony for his 40th birthday bash in New York that same night: Dita Von Teese, Leah Remini, Paulina Rubio, salsa legend Johnny Pacheco, Brooke Shields, supermodel Veronica Webb, style icon Kimora Lee Simons and fashion designer Donatella Versace were just some of the glitterati in attendance at the party, hosted byJennifer at the Bowery Hotel.

The royal couple themselves, fresh off their flight from L.A., arrived in garb more suited for a wedding than a birthday bash—Jennifer rocked a flowing white gown while Marc donned a grey tuxedo. The couple even stole a trick from their joint concert tour last year and switched their outfits midway through the party: Jennifer put on a more party-appropriate minidress and Marc shedded his vest and bowtie and—you guessed it—unbuttoned a few of his shirt buttons.

We're glad that their entourage of bodyguards, assistants, trainers and party planners as well as their private jets and limos help Jennifer and Marc be there for each other for the important moments in their lives. You know what they say: The couple that spends together, stays together.
