Both Olivia and Jason looked stunning in matching black-and-white monochrome looks.

Unfortunately, the “Save the Last Dance” actress’s gown appeared slightly wrinkled, which could have been fixed with a quick steam.

Nevertheless, the “Scandal” actress still looked fabulous, especially with her cascading waves, berry lips, and diamond jewels from Jennifer Meyer.

The 37-year-old actress (who is unrelated to Denzel Washington, if you were wondering) wore the “Pigalle Strass” pumps from Christian Louboutin, which feature crystal embellishments, pointed toes, stiletto heels, and the brand’s signature red leather soles.
