Ashlee Simpson Talks About Jessica

Ashlee Simpson-Wentz approves of her sister Jessica’s new football boyfriend, Eric Johnson.

On Thursday Night at the Neil Lane/Kay Jewelers party at Drai’s Hollywood Ashlee told UsMagazine.com, "She is happy, so we are all really happy.”

Ashlee, 25, recently celebrated Jessica’s 30th birthday in Italy, "Her happiness is the most important thing to me.”

She also revealed Jessica is not planning to have any children of her own with her new guy of six-months.

"She does love being an aunt though. She is a great aunt. Yesterday he was over at her house calling her 'Jess' [and then saying] 'ica' a few minutes later. It was really cute."

Ashlee and husband Pete Wentz of Fall Out Boy welcomed their son Bronx Mowgil in November 2008 and, unlike her sister, “definitely” plans on expanding her family.

"We would love to have a big family,” she says but is unsure about how many kids she wants because “You can never plan something like that."

Ashlee raved about her son and how quickly he is growing up.

“Every day is like a milestone, I swear. It is the best thing. I mean, being a mother, taking the time that I have taken off just to be with him has really been incredible. Every day he is learning something new and growing. It is fantastic. I feel very fortunate."

She added, "We paint. He loves the water hose outside. That is always exciting, especially because it is extremely hot outside right now. We write on the walls with chalkboard and chalk. It is fun and it keeps you active because every day you're thinking, 'What are we going to do?' Even if it's just dancing in place. He is really cute. He is really becoming his own little man."

Bronx likes music. His favorite is Jay-Z.

"He loves Jay-Z. He says, 'Jay-Z ma ma.' So we do the ones without the swear words."
