Most of tu who watch gossip girl also watch one árbol hill.(me being one of them)I found a one árbol colina schedule for the rest of season 6 and since one árbol colina and gossip girl usually have the same schedule, i thought this might apply to gossip girl to.So here's one árbol hill's schedule....
2/09-rerun
2/16-rerun
2/23-rerun
3/02-rerun
3/09-new ep.(6x17)
3/16-new ep.(6x18)
3/23-new ep.(6x19)
3/30-rerun
4/06-rerun
4/13-rerun
4/20-new ep.(6x20)
4/27-new ep.(6x21)
5/04-new ep.(6x22)
5/11-new ep.(6x23)
5/18-FINALE!!

So,yes there is another break coming,for árbol hill, but like i dicho i'm not sure about gossip girl's.this should be similar to gossip girl's schedule,since like i said,they usually have the same schedule but,i'm not sure.One árbol colina starts up again a week before gossip girl,but gossip girl is ahead of oth an episode.OTH starting a week earlier will make them even,therefore,gg could have the same schedule.If tu have any info on the gossip girl schedule,please comentario below,to let me know. : )
