And though she mingled with Devon Windsor, Raissa Gerona and Lais Ribeiro, the star – who works with FWRD and had her 818 Tequila served at the fete – cut a lonely figure as she did not appear to have a plus one.

It has been over a month since the star was seen with her boyfriend, singer Bad Bunny, which has led fans to speculate that they have split.

The rapper may, however, just be back in Puerto Rico to spend the holidays with his family.

At the Revolve event, Jenner wore a black jacket that was tied at the waistline, adding leggings. She wore her dark hair down and had on mauve lipstick

In November Kendall posted to social media what appeared to be a breakup note.

She shared an image of a sunset; there were no people in the photo.

‘What’s meant for me, will simply find me,’ the Kardashians star captioned the post.

Fans rushed to guessing about her love life: ‘Sounds like a break up post,’ one fan wrote while another stated: ‘She and Badbunny just break up.’

The last time she was seen with him in public was in late October at the Beverly Hills Hotel.

There were several other lovely ladies at the Revolve event in Colorado.

Windsor was pretty in a scarlet red dress on with a matching coat and ‘mules’ shoes with a buckle on top.

The swimsuit designer even carried a red clutch purse.

She also was seen posing with fellow Victoria’s Secret model Lais Ribeiro who opted for an all-black look.

Stella Maxwell, who used to date Kristen Stewart, wore a black leather outfit with a blue top.

Mauricio Umansky looked to be having a great time as well.

The estranged husband of Kyle Richards smiled as he put his arm around a pretty pal who wore a hat that read, ‘We’re all mad here.’

The 53-year-old Real Housewives Of Beverly Hills guest star pointed his hand toward the blonde woman as he smiled away.

Mauricio and Kyle are living under the same roof in Los Angeles, but are leading separate lives as they are trying to figure out what to do with their marriage.

Mauricio wore a blue and cream colored plaid jacket was left unbuttoned as he had a dark gray T-shirt underneath.

The real estate agent who owns The Agency added dark gray slacks and a beaded necklace.

His female friend wore a beige suede fringed jacket with a beaded star on the shoulder and Native American designs on the pocket.

She added a pink tank top and worn-in jeans while flashing turquois and silver jewelry as she held onto a beverage.

Earlier this week Richards said she is trying to ‘figure out’ what to buy her estranged husband for Christmas.

The 54-year-old reality star split from businessman Umansky – with whom she has daughters Alexia, 27, Sophia, 23, and 15-year-old Portia – in July after almost three decades of marriage.

But she has insisted they are still on good terms and she is even spending Christmas with him this year.

She told E! News: ‘I definitely will be giving him a gift if we’re spending Christmas together. I just have to figure out with that gift would be.’

Mauricio Umansky looked to be having a great time at the Revolve + FWRD Pop-Up Shop party in Aspen, Colorado on Thursday evening. The estranged husband of Kyle Richards smiled as he put his arm around a pretty pal

The Bravo star previously admitted that ‘fighting’ was not what led to her marriage breakdown but admitted that when the new year rolls around, she just wants ‘peace’ within her family after enduring such a ‘rough’ time over the last 12 months.

She said: ‘Like with most relationships, first and foremost we’re friends.

‘Our relationship, any issues we had it was never fighting. Disagreeing about things was not our issue ever.

‘This sounds cliché, but I really just want peace, I really do.

‘This has been a really rough year going through so many difficult things in my personal life and so much scrutiny.’

The comments came just days after Kyle revealed that even though she and Mauricio will be spending the holidays together despite their split, she is still hesitant about the idea of them ever reconciling for good.

Speaking to TMZ after a family outing to the popular shopping and dining destination The Grove in Los Angeles, Kyle said she and Mauricio are getting on ‘good enough to go to The Grove’.

Asked about the chances of them getting back together, Kyle told the outlet when she was stopped outside Beverly Glen Deli earlier this month that they are ‘just taking everything a day at a time.’
