The newest TNA Knockout is "Rebel" from The Menagerie.
Rebel is really a former Dallas Cowboys cheerleader, Tanea Brooks.
Tanea is a longtime friend of current TNA Knockout Christy Hemme.
They were both in the dance group "Purrfect Angelz" before Christy started wrestling.
Tanea appeared on the Full Throttle Saloon TV series and in the Trace Adkins' "Honkey Tonk Badonkadonk" and in the Brooks and Dunn "Play Something County" music videos.
She has been training with Ohio Valley Wrestling but I'm guessing that her character Rebel will be more of a manager/valet.
And in case you didn't notice, she is kinda flexible...
