Well, "Glee" fans, boss Ryan Murphy has joined Twitter and he's provided us with an embarrassment of riches in the last two days. Assuming that he's not intentionally misleading fans -- as he's been known to do, to protect show secrets -- here are some of the details he's revealed since joining the world of social media.

Sam and Mercedes are dunzo. The on-again-off-again couple has split for good now that Mercedes has graduated from McKinley High. "SAM will have a new girlfriend this year. Guess who it is!" teases Murphy.

Expect a super-sized Thanksgiving episode. Murphy is planning a two-parter for Thanksgiving, as Sectionals fall in November this year.

Someone's splitting up! The writers are working on an episode called "The Break-Up" that Murphy says he's "really excited about." We know that the break-up doesn't refer to Sam and Mercedes -- that's over before the season starts -- so who could it be?

Kurt is going Vogue. Anna Wintour is collaborating with Murphy when it comes to Sarah Jessica Parker's wardrobe for the show -- and it sounds like she's also given her blessing for to become a major factor in the series, because Murphy hints that Kurt will "thrive" working there under the tutelage of Parker's character.

More Adele, more Britney. The first group number of the season will be Adele's "Chasing Pavements." Lea Michele also reveals that she recorded a classic Britney Spears song for another tribute to the pop star.

Murphy also tweeted this pic of Michele and Chris Colfer. Where could they be?

As if that wasn't enough news, TVLine reports that Becca Tobin and Melissa Henoist have been cast as two new McKinley High students named Kitty and Marley. Perhaps one of them is Sam's new lady?

沪江娱乐快讯：《欢乐合唱团》的粉丝们注意咯，制片人瑞恩?墨菲（Ryan Murphy）加入“推特”（ Twitter）啦，他这两天可是给我们爆了不少第四季的料。如果他没像以往一样故意误导粉丝的话，我们就来看看他在推特透露的剧集信息吧！

萨姆（Sam）和梅塞德斯（Mercedes）掰了.这对分分合合的情侣终于随着梅赛德斯的毕业永远说拜拜了。“接下来萨姆会有个新女友，猜猜会是谁呢？“墨菲故意吊大家胃口。

今年的感恩节合唱团将会故事多多！十一月刚好是合唱团地区赛落幕，墨菲正计划以“感恩节”为名制作上下两集。

有人要分手？编剧们正在酝酿名为“分手”（The Break-Up）的一集，墨菲在推特表示“很兴奋”。我们知道萨姆和梅塞德斯远在第四季之前就拜拜了，所以哪对情侣或朋友会被编剧们狠心拆散呢？

科特（Kurt）要去《Vogue》工作了！因要为莎拉?杰西卡?帕克（Sarah Jessica Parker）在该剧的客串角色准备服装，《Vogue》主编安娜?温图尔 (Anna Wintour)与墨菲在第四季有所合作。而似乎这位“时尚女魔头”还允许Vogue的名头被该剧大为利用，因为墨菲暗示科特将在《Vogue》与莎拉?杰西卡?帕克饰演的角色共事，并且混得风生水起。

第四季将演绎更多阿黛尔（Adele）和布兰妮（Britney）的金曲。新一季里的首支合唱曲目即为阿黛尔的“Chasing Pavements”。主演丽娅?米雪儿（Lea Michele）还透露她已录制一曲小甜甜布兰妮的经典曲目，再次向这位大明星致敬。

墨菲还在推特放了一张瑞秋（Rachel）和科特的剧照。粉丝们猜猜他们这是在哪儿呢？

如果以上剧透你还没看够，《TVLine》杂志还带来一条新闻，贝卡?托本（Becca Tobin）和梅丽莎?汉诺斯特（Melissa Henoist）两位银幕新人将出演麦肯利高中（McKinley High）新生，其中一个可能就会是萨姆的新女友哦!
