Ashlee Simpson

Pop singer Jessica Simpson has said that she "couldn't be happier" about her sister Ashlee's engagement to Mr. Pete Wentz.

News of her engagement to Wentz was revealed 'to fans' by Ashlee herself.

Though their father Joe Simpson has been reported as not favoring 'Fall Out Boy' bassist Wentz, it just has not stopped Jessica from being happy and pleased for the young couple.

Jessica, who had been married to singer Nick Lachey for three years before divorcing, revealed that she is very ecstatic about the whole thing.

"My sister is overflowing with joy.

Pete is an incredible soul, The Sun quoted her as saying.

"They naturally bring out the best in each other.

I couldn't be happier, she added.
