Yesterday at early hours Mark was tweeting a bit and this is what we could read when we came online.
From oldest to newest...Heres something to make you laugh
http://bit.ly/aHiVK I never laughed so hard as when I first seen it!
I love you ALL more than u cud ever know! LOL u are forgiven,just don't do it again hehe! I'm off2read my book 'dying to survive' nite X
Aww... we love you (and your lovely boyfriend) a lot too Markie

Some of us feel we missed something before the last tweet, don't we? Ok! we're right. According to some fans, Mark tweeted something before but, for some reason, he deleted his twits. However, Rachel
@the forum told us that it was about that person pretending to be Barry (one of his younger brothers). Apparently, a fan asked if it was his brother and Mark said no, and got a bit annoyed that someone was pretending to be his brother. We can understand him.
We will never understand what motivate people to pretend to be someone who they really aren't, but be careful because Barry is not the only one, there's lot of fakes profiles around pretending to be Kevin or Mark.
