Jessica Simpson Still 'Jumbling' Wedding Dates

ET was there as Jessica Simpson appeared with First Lady Michelle Obama at an event for military families and revealed that she just started to consider possible wedding dates a few days ago. 

The singer -- who performed an emotional rendition of "God Bless America" for about 250 military families at Coors Field in Denver -- said she is still trying to nail down a date for her wedding to her fiancé, former NFL football player Eric Johnson.

"I am planning a wedding, I mean I'm starting to. I hadn't started until two days ago, I was like 'okay, I'm going to jumble around three dates before the end of the year and see what fits for everybody in my life. So we'll see what happens, but I know that I'll definitely be married by the end of the year," Simpson said. 

First Lady Obama thanked Simpson for attending the event, in which the children of military service members were given the chance to interact with her and the singer and also watch a major league baseball game on jumbo screens and take part in games and activities at the stadium where the Colorado Rockies play.

Vice President Joe Biden's wife Jill also attended to promote a White House initiative aimed at encouraging all
Americans to support military families. For more information and to get involved with the Joining Forces initiative, click here. 

"I am very honored and very blessed to have been asked by Mrs. Obama herself to come here and to help launch this initiative, which I believe in so much. So I'm so glad that I was one of the people she chose to stand in support for this," Simpson said.
