Jennifer Love Hewitt (JLH) and John Mayer (JM) are two freaking hot messes that are in desperate need a dating intervention. These two knuckleheads are famous (some might argue more than they should be) for their constant inclusion in celebrity gossip. And since I am guilty of loving my gossip mags, I feel compelled to throw my two cents in over what assumptions I have made from the media. Sounds super scientific, right? 
These two unlucky in love losers briefly dated in 2002. Rumor has it that JLH sent some fancy bouquet of balloons and candy to one of JM's recording sessions. Apparently it worked. Personally, it kinda sounds to me like a gesture that is better suited for a 6 year old birthday party and not someone you want to bang.
JM had recently ended a very brief affair with songstress Vanessa Carlton. It isn't surprising that JM and Vanessa did not last. After all, this was a time when each of them just launched their first major label cds. Rumor had it that their relationship was doomed in part due to a little game of "who is doing better in the charts" rivalry.
In 2002, pictures began circulating around the gossip circuit with JLH and JM together. This lead a ton of people to incorrectly claim or hint that the song "Your Body is a Wonderland" was about JLH. Just so we are clear, he wrote that song years before he even met JLH as it was included in his first non-major label release in 1999. At the very most, he was wanking it to her image from tv shows or the movies.
Ok, so I have an enormous amount of JM information! I admit it! I used to be a huge fan of his back around 2001, used to send him porn while he was touring (the ingrate never thanked me, but I did become known as 'porn chick'), and met him a few times. Even back before he hit it big, he had a reputation of sleeping with his fans.
Since the time JLH and JM dated, she has been engaged at least twice (if not more, I lost count), and he has remained the bad boy bachelor. Part of the reason I have such a strong dislike of JLH is that she appears to be a love addict. Everything I have heard or seen written about her makes her out to seem completely desperate, insecure, and clingy. At least it seems that way to me.
I also really don't like that she is one of the main reasons the word "vajazzle" exists. As a sex educator, I know that vaginas are an internal structure only. Maybe I could go at her with a hot glue gun, a speculum, and some swarvoski crystals for her to get that what she is talking about is mons jazzling. 
JHL needs a dating intervention at best or some serious therapy around being a love addict at worst. The fact that she is 32 and has had a few broken engagements isn't really that big of a deal. The reasons behind her broken engagements, however, is a red flag.
On one hand she is probably smart to have never gotten married because it is highly likely she would be divorced by now. She is probably glad to have dodged the epic Kim Kardashian marriage fail bullet. But it does make me, as a dating coach, wonder why she chooses men who she is clearly incompatible with.
I think her bottom line is that she is in love with love, and moves full steam ahead when she finds someone new to date. The problem with this game plan is that people are usually on their best behavior during the courtship period and aren't always being completely sincere and authentic. For example, someone you are newly dating is most likely gaga over you, wants to spend a lot of time together, and is probably pretty generous with compliments. What was once "Wow, I love the way you treat and take care of me" can quickly become "Why don't you compliment me anymore, why are you so busy, and who else are you hanging out with". I'm not saying that her clingyness and insecurities are the reason for her failed engagements. Ok, well maybe I am. The bottom line is that JLH needs to be be secure, confident, and really like herself before anyone else can truly love her.
My dating coach suggestion is that she spend a lot more time on herself and a little less time chasing love.
Now JM is a whole other ball game. He is a narcissist with boat loads of money, an allegedly big dick, and has the ability to literally charm the pants off of you. He is also someone who brags about his conquests in excruciating detail, making many of his past lovers cringe. Incidentally, he was rumored to be gay or enjoy a little man on man action
years ago, but I think that rumor has mostly gone away.
Let's face it, JM is a douche bag. Even HE admits that he sounds like a monster douche after reading things about him. I hear he has a google alert for his name, too. The google alert doesn't appear to be working as he is still mostly thought of as a cad.
My dating coach prognosis for him is not great. There is little you can do for someone who is narcissistic. However, I do know that he needs to stop dating other celebrities! Vanessa Carlton, JLH, Jessica Simpson, Heidi Klum, and Jennifer Aniston have all been romantically tied to him. What he really needs is a good kick in the ass. He needs to stop seeing the women he dates as trophies and inanimate objects and nut up. He is a 34 year old man who still acts like he is 14. Maybe he suffers from arrested development because he began non stop touring when he was young and it consequently made it difficult to form real relationships. 
It's funny and pretty rare that I can become so annoyed by others that they prompt me to write a freaking long blog post. Maybe it's me who really needs an intervention?
