New Kids On The Block selling out Madison Square Garden. Janet Jackson releasing a new song. What year is this again? 

The boy band (can we call them a man band at this point?) sold out MSG two nights in a row, giving fans the ultimate throwback experience by having the two surviving members of TLC, T-Boz and Chilli, take the stage before they went on. T-Boz and Chilli performed three songs, ending with "No Scrubs," which had the whole stadium singing along.

And Monday night, Mark Wahlberg joined the guys on stage, the first time he's done so in more than 20 years. Then, as if that wasn't enough, rapper 50 Cent made a surprise appearance and everyone launched into "Just A Friend," followed by "In Da Club."

Well, we'd say the fans got their money's worth, wouldn't you?
