Movie with the line: "How long has it been?" " don't tell or i'll have to strangle you"?

There's a fairly recent movie that came out with with two women that were enemies in highschool and one of them is a *****. In the previews the bitchy women acts fake and gives a hug to the other women and says "how long has it been?" and then whispers in her ear "dont tell or i'll have to strangle you" ..... it's a comedy
