Jessica Simpson, Eric Johnson celebrate engagement

Washington (ANI): Jessica Simpson and Eric Johnson celebrated their nearly-week-old engagement at a party with their close friends and family members at the bride-to-be's parents' house. About 50 guests, including a few NFL players, dined on hamburgers, veggie burger sliders, mini pizzas, chicken skewers and mini cupcakes for dessert, reports Usmagazine.com.

"They were very happy," said a friend of Simpson. "It was the first time they had seen a lot of their friends since the engagement. She was excited to see her girlfriends, " the friend added.

The couple began dating in June, when Johnson was separated from his wife Keri. Simpson split from ex-husband Nick Lachey in 2005.
