First of all, since it was Gwyneth's 40th birthday this was back in 2012. Before the GS era, during the MX tour. So just because he did it back then doesn't mean he still does it now. Also just because he did it on a party doesn't mean he smokes/smoked weed everyday, maybe he just does it/did it at parties or that one time(doubt it that it was a one time thing though). I don't know him personally but I doubt that the first time he tried it was back in 2012, I believe it was much earlier (that's the life of a "rockstar" ,although the guys were tamer since they did promise each other they wouldn't do hard drugs and they never had that rockstar image) so if he was hooked I think he would have been years ago and not just now in the AHFOD era. It just annoys me that just because someone is all about love and unity, has a more positive outlook on life and their songs our happier that it is considered a "hippie style".
Secondly, I am a curious person (with a lot of free time on my hands lately and I love detective shows haha ) so I had to search if during September 20- September 30 2012 (Gwyneth's birthday is on September 27th) Chris was on the same place as Lady Gaga. Lady Gaga was in France on September 22th 2012 and Coldplay was in Germany (the last time they had been in France was in September 2nd. Lady Gaga was also in Germany on September 20th 2012 but she had the concert in France after that so I doubt they had any time to meet, they were also in different cities). After this, Coldplay didn't have a concert until November so they could have easily gone to France again. But Lady Gaga had a concert again on September 24th in Germany.So she couldn't have stayed long, she probably had left by September 23th. I doubt that Coldplay would go one day after their last concert to France or if they did it would be really hard for them to meet with Lady Gaga. So I don't know how he could have got it from her.
This probably looks like I am defending Chris but what I am trying to say is that we shouldn't believe people who claim things, think if they could gain something from it( be more relevant by mentioning Coldplay's and Lady Gaga's names, because who knew her before this? ) and that if it's true we shouldn't judge a person just by something he did once.
I rest my case.
