Quite the dramatic look Jessica Simpson was rocking there for a morning show interview.

The hotter-than-ever mama showed up for her sit-down with Today's Savannah Guthrie, airing Monday, in a long black dress from her Jessica Simpson collection that boasted a plunging V-neckline and a thigh-high slit up the left side.

And why not?

The Weight Watchers spokeswoman has been working hard (on both her body and her entrepreneurial pursuits) since giving birth to son Ace last June, so she deserves every chance to show off the fruits of her fitness labor.

Simpson accented the look with matching gold cuffs, perfect for the Forbes Women's Summit in NYC, which she attended after her Today taping with fiancé Eric Johnson.

"Loved chatting with entrepreneur and fashionista@jessicasimpson - interviews airs Monday@todayshow," Guthrie put on Instagram along with a pic that showed off her own growing baby bump.

Simpson polished her own powerful-woman prestige by attending the White House Correspondents Dinner earlier this month—aka her and Johnson's "first date since having baby Ace," which is how she referred to it on Instagram.

The couple sat with the USA Today group and Simpson stunned in a strapless Carolina Herrera gown.
