The 31-year-old Fall Out Boy bassist was spotted having lunch with his estranged wife on Valentine's Day, but a more permanent reunion might not be in the cards.
Ashlee Simpson-Wentz filed for divorce from Wentz, who is the father of their 2-year-old son Bronx, after more than two years of marriage.
Ashlee Simpson-Wentz, the 26-year-old sister of fellow pop singer Jessica Simpson, cited irreconcilable differences as the reason for the split, court documents show. She is seeking joint legal and primary physical custody of Bronx, as well as spousal and child support.
The two married on May 16, 2008 at her parents' home in Encino, California. Their son was born the following November.
"Dont forget 2 notice-when i look into the lil dudes eyes & smile, the way he loves. i realize @ashsimpsonwentz is a good moma + so much more," Wentz wrote on his Twitter page on Monday, ahead of the divorce filing.
It has been said that Wentz was blind-sided by the filings and was seeking to make ammends with the mother of his child. Neither Wentz, nor Simpson-Wentz have commented on the reports.
