"irrelevant; only what the world calls her matters. So I checked Google News: 2,753 hits for ""Ashlee Simpson"", 489 for ""Ashlee Simpson-Wentz"". I feel this demonstrates that ""Ashlee Simpson"" is still the correct title. Does anyone oppose moving it back?   

I was going to say the same thing. Her legal name is irrelevant, this article should be at the most commonly used name that most people know her by, which is obviously Ashlee Simpson. 92.1.2.237  
Yes, and even her official website still calls her ""Ashlee Simpson"".   

I will move the page back to ""Ashlee Simpson"" in 24 hours unless there is an objection, or unless Google News indicates a significant trend toward general adoption of the ""Simpson-Wentz"" name.   

I searched Ashlee Simpson as Ashlee Simpson-Wentz and pages are starting to refer to her as Ashlee Simpson-Wentz. Let's keep the article as-is.  —Preceding unsigned comment added by 24.151.137.19   

Yeah, I've searched her as Ashlee Simpson-Wentz in Google News, and they've started referring to her as Ashlee Simpson-Wentz. The article is fine the way that it is.   

You can see the numbers I posted a few days ago above. The current numbers are 3,358 for ""Ashlee Simpson"" and 559 for ""Ashlee Simpson-Wentz"". I don't see a trend towards the latter. Most of the newest articles refer to her as ""Ashlee Simpson"".   

Considering that she got married a couple weeks ago, I think that 559 results as Ashlee Simpson-Wentz is a good number of articles. It will probably increase as more articles are written.   
If that were the case, we'd see a trend, but what I see is that there was a spike in the use of the new name after it was announced, but that subsequently most sources continued to use the old name. The results indicate to me that the new name hasn't caught on.   

Read this: 
she's taking Pete's surname and is going by Simpson-Wentz professionally. I think this settles this dicussion. 24.151.137.19  
The point is that it doesn't matter what she calls herself. Wikipedia articles are titled according to the common name of the subject.   

Exactly. Ashlee is changing her common name. 24.151.137.19  
She can't change her common name. Her common name is decided according to what people want to call her. If they now start calling her Ashlee Simpson-Wentz, then that's her new common name, but if they keep calling her Ashlee Simpson, then that remains her common name. That's why I've been comparing Google News results, to see whether this new name is really catching on. Also, as I pointed out, her website still uses her old name, but maybe they're just lazy. Since there are two of you in favor of keeping it at this title, I propose that we wait one week, then look at the results again and see if there's more of a shift towards Simpson-Wentz.   

I just noticed that Danny has been going around changing the articles on her albums so that they are described as Ashlee Simpson-Wentz albums. Considering we don't even have a consensus on what she should be called now, I don't think it's appropriate to try to extend the Simpson-Wentz name to album articles which were released under the Ashlee Simpson name before she married Pete.   

I've searched Google News for Ashlee Simpson, which had 3,162 results, and Ashlee Simpson-Wentz, which had 1,613 results. So clearly, the results for Ashlee Simpson are dropping while results for Ashlee Simpson-Wentz are increasing. But, as Everyking said, he
