So "Live Earth" brought us good music with a peaceful message, like saving the planet and stuff. It looks like this event has brought much more to the (now) blonde Ashlee as her boyfriend, rocker Pete Wentz, who asked her to marry him. According to sources, Pete did it like in the movies, on one knee and with a huge ring. Also, some say that Ashlee is also pregnant, that's why the sudden hurry over the wedding. The couple tried to keep everything hush-hush, as they feared that media attention might, in time, ruin a potential marriage, like it was speculated in the case of her older sister, Jessica.

In case you don't remember right now, Jessica Simpson is 26 years old, and she married (while still a virgin, she says) Nick Lachey. They divorced three years later for "irreconcilable differences". Guess she wasn't that good in bed. Ah, the lack of experience... After this high-profile break-up, she supposedly dated actor Dane Cook, rocker Adam Levine and guitarist John Mayer. Currently, Jessica is probably single, as she split-up with John in May. But let's get back to Ashlee...

So, Ashlee Simpson has always posed as much wilder than her sister. She had a show on TV and some affairs with various men, like actor Josh Henderson, musician Ryan Cabrera, soccer player Wilmer Valderrama and many others. But it looks like freedom is done for Ashlee, and at such a young age. Well, if it doesn't work with Pete, she can always imitate her sister and file for divorce. Although in June she claimed to Cosmopolitan that she is single, it appears that she...well...lied. Or even worse, got engaged with someone she just met. Well, a little white lie to protect the privacy never hurt anyone.

And about her pregnancy, sources say that the rumor was started at a party when she kept rubbing her belly and refused to drink alcohol. That doesn't really mean much, but we'll keep a look out for additional dirt. By the way, her rep denied everything, from the engagement to the baby. That doesn't mean much either, as these starlets have a bad habit of lying through their teeth for a "higher purpose"...
