Jessica Simpson Rains on Tony Romo’s Parade

She might be making waves on the other side of the globe, but Jessica Simpson can’t even keep a date with her boyfriend here in the States.

Simpson designs clothing, shoes and handbags for Macy’s, and was supposed to fly from Nashville to New York yesterday to celebrate the department store’s 150th anniversary, reports People.

However, her initial flight got rained out. So Macy’s and Sesame Street’s Elmo were spared hearing her flub the lyrics to “Happy Birthday.”

She did eventually show, saying “Tony [Romo] was just praying [that I wouldn’t make it out]. He had planned a really romantic date in case I didn’t make it [to New York] tonight.”

Oh, well. Maybe she got wasted and made out with Elmo instead…
