Where can i watch the new episode (ep18, season 2) of gossip girl?

i cant find it anywhere! :( its not on sidreel and i checked ov guide and loads of different websites. i want to stream it, not download it - preferably on megavideo (all the links to megavideo i've tried dont work cos its been removed due to copyright infringement) it also has to be free, which watch-gossip-girl.com isn't. also im in the uk so i cant use hulu, cw website, etc... thank you!!!
