Tamar Braxton glammed it up in Diane Von Furstenberg around 4AM this morning for the live broadcast of the Steve Harvey Morning radio show in Vegas.  But Skylar Diggins rocked this DVF look first in the Hamptons.  Decide who ran it inside....

Tamar Braxton wore a Diane Von Furstenberg black & nude lace jumpsuit to perform on Steve Harvey this morning at the Mandalay Bay Convention Center.  The 36-year-old sang live during the 3AM-7AM broadcast straight from Vegas, and she didn't skimp on the glam factor for her 4AM performance.  Tamar rocked a pendant necklace, bracelets and rings to complete the look.

But 23-year-old WNBA star Skylar Diggins rocked this cute DVF jumpsuit first a few weeks ago at the 14th Annual Art For Life Benefit.  While posing it up with her fellow Roc Nation teammate Melanie Fiona, Skylar kept her arms & neckline bare as she rocked a gold clutch and cris crossed sandals.

So....

WHO RAN IT?!
