The 'Pretty Little Liars' Finale And Britney Spears On 'Glee' In Today's Tweet Dreams

No secret here: We can't wait to find out what happens on tonight's mid-season finale of "Pretty Little Liars." While we count down, the show's stars have been teasing us all day. Shay Mitchell wrote to fans, "Hope everyone is enjoying the #PLL marathon today and then the mid season finale tonight! Woowhoo!!" while Keegan Allen has us talking with his juicy tweet, "Pretty Little Liars Summer Finale. You will be telling your children's children about it. Wow, your in for it now."

Yes, we'll be sad to say goodbye to "PLL", but at least we have season two of "Glee" on the horizon! With the official countdown started, our excitement has only been heightened with the news that broke yesterday that there will be an all-Britney Spears episode of "Glee." Today, Ryan Seacrest caught up with Ryan Murphy and told followers, "Spoke to @gleeonfox creator ryan murphy. Said @britneyspears will appear on glee. Also no plans yet but wants to do Prince, Beatles & MJ eps."
