The 37-year-old looked amazing in a nude coloured jumpsuit which perfectly accentuated her slim figure.
She finished off her fierce look with a pair of Gucci thigh high boots with tie detail at the top and a pair of dark sunglasses.
Tristan’s most recent misdemeanour is the third time he has cheated on Khloe, but pals say this time she is “really struggling”.
The professional basketball player admitted he had fathered a son with personal trainer Maralee Nichols following a brief affair in March 2021 while he was in a relationship with Khloe.
It is the third child for Tristan, who is also dad to daughter three-year-old True with Khloe and son Prince, five, with model Jordan Craig.

Khloe was spotted looking at baby clothes during the LA shopping trip with her model sister Kendall Jenner.
This sparked rumours pregnant sister Kylie Jenner, who is due to give birth to her second child any day now, is having a girl.
But it was Khloe’s outfit on the trip that really did the talking – and there’s no denying the mum-of-one is looking better than ever.
It is the second incredible look she has unveiled this month since the full extent of Tristan’s cheating was made public.
In social media snaps shared with her 216 million followers last week, Khloe posed in a sheer white mini dress and brown knee high boots.
Her perfectly styled two-tone blonde hair hangs loosely by her shoulders in the sultry snaps which were a big hit with fans.
One wrote: “I’m living for this HAIR, you look beautiful” while another said: “Queen of Calabasas!!”
He wrote: “Sometimes you don’t realise your own strength until you face your greatest weakness.
“Hide from your demons and they’ll slowly destroy your potential. Face them and they can potentially become your greatest asset.”
When his paternity results came back proving he was a father again, Tristan issued a grovelling apology to Khloe.
He said: “I take full responsibility for my actions. Now that paternity has been established I look forward to amicably raising our son.
“I sincerely apologize to everyone I’ve hurt or disappointed throughout this ordeal both publicly and privately.
“Khloe, you don’t deserve this. You don’t deserve the heartache and humiliation I have caused you.”
He continued: “You don’t deserve the way I have treated you over the years. My actions certainly have not lined up with the way I view you.
“I have the upmost respect and love for you. Regardless of what you may think. Again, I am so incredibly sorry.”
