The reason why Summer Rae and Layla have been teaming up as of late is because they're seen as the new version of the once-popular Diva tag team Lay-Cool.

It's said that part of the reason for this move was the fact that Angelina Love and Velvet Sky have reformed The Beautiful People over in TNA. The idea was that the WWE couldn't reunite Lay-Cool and so they put Layla with the Diva who looks a lot like Michelle McCool.
