Ashlee Simpson and Pete Wentz Just "Grew Apart"

It's the third shocking celeb split this week and of courses there are lots of 'sources' telling the press what's going on!

Ashlee Simpson and Pete Wentz announced that they were divorcing yesterday after two and a half years of marriage. No reason was given at the time, but sources close to the couple say nothing bad happened between them they just "grew apart". The insider says:

"It's very amicable. They're on very friendly terms and speaking - it's fine. They've just grown apart. They've been growing apart for quite some time. They're both really sad. It's a sad ending to something that was really promising. They're each trying to figure out what this transition is going to be like."

When the news was announced yesterday there was speculation growing that the pair had engaged in constant drunken fights over the last few months, most notabley a fight took place in public when Ashlee threatened Pete's ex, Gossip Girl star, Michelle Trantenberg.

However, this insider says there was no on-going fights and that all they want to do is take care of their 2-year-old son Bronx, adding:

"It's all about Bronx for them. They're fantastic parents - Pete says she's a great mum, and she says he's a great father. It's about Bronx's care and well-being and happiness for them."

The whole break-up seems to have come out of nowhere, with the couple looking very much in love at recent public appearances. Also, on Monday Pete had Tweeted this:

"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"

Sounds to me that he's really sad. Ashlee is the one that filed for divorce, is there something we're missing here?
