Jill and Bethenny'Real Housewives of New York' star Jill Zarin has apologized for accidentally breaking the news of the birth of co-star Bethenny Frankel's new baby girl and for getting the baby's gender wrong, NY Daily News reports.

"Yesterday [my daughter] read a tweet and blog that Bethenny gave birth," Bethenny's famous frenemy posted Saturday on Facebook. "We were excited and congratulated her obviously prematurely. I should have waited until B announced it herself. Sorry."
