Kourtney Kardashian attended the Variety & Women's Wear Daily Inaugural Stylemakers luncheon at Smashbox on Thursday morning. During the event the hot mama spoke with E! News' anchor Catt Sadler and gave an update on her sister's health. Khloe Kardashian was forced to reschedule her book signing after her doctor advised her.

The 36 year old Kourtney confirmed that the Strong Looks Better Naked author is currently doing okay, although "she's not feeling well." She said that Khloe has "experienced fever, fatigue, and swollen glands. She has an infection but hasn't been diagnosed yet."

The mother of three who recently broke up with Scott Disick after being together for nearly a decade went to the event in an olive green two piece. The dress perfectly highlighted her sexy figure, a fruit from her intense workouts and diet.

During the event, the Keeping Up With The Kardashians star turned heads and was complimented on her svelte physique and revealed to the publication, "I've been working out." But "Today I didn't work out, but it makes me not feel anxious. Today I was in the shower and feeling anxious like, I needed to work out."

The Dash co- owner further revealed to E! that she's in good spirits following her recent split from her former man but confessed her recovery "depends on the minute." Further adding that everything she's been through "happens for a reason."

Another star who went to the event is Tom Cruise's ex, Katie Holmes, who looked stunning in a black silk shirt with oversized black and white skirt. The actress looked classy with her hair parted in the middle and some bangles on her wrists. She paired her outfit with a pair of pointed black shoes.

Other attendees included, Kerry Washington, Cara Santana, Viola Davis and Fredia Pinto, who stood out in a neon yellow dress that had a hem above her knees.
