Kimora Lee Simmons continues living the fabulous life in Vegas ... amid rumours of split from actor beau Djimon Hounsou

Former model and businesswoman Kimora Lee Simmons has been living it up in Las Vegas despite a reportedly troubled personal life.

The 37-year-old beauty looked gorgeous as she arrived to host the Carnevale Grand Summer premiere at the luxurious Palazzo hotel on the strip.

Simmons' partying comes hot on the heels of reports she has split from her beau, African born actor Djimon Hounsou.

The leggy brunette looked svelte in a gold and beige minidress and heels and got into the spirit of the festival, posing with a resplendent masquerade ball mask of jewels and feathers and having fun with the performers on the red carpet.

The actor, star of hits like Gladiator and Blood Diamond, got his big break as slave Cinque in Steven Spielberg's Amistad in 1997.

According to the New York Daily News, Honsou walked out on SImmons after "a big fight over money".

Reports also claim Simmons' former husband, hip-hop mogul Russel Simmons, decided to stop funding the pair's lifestyle.

While Simmons while all smiles at the Palazzo, she was said to be already feeling the pinch.

The Trulia Luxe Living blog reported that she is selling her Beverly Hills home at a $1.2m loss.

 Representatives for both Honsou and Simmons are keeping quiet about the alleged split.

Honsou's agents told nydailynews.com the actor has been working in Vancouver for the past few months, and Simmons' people responded only that 'Kimora has a beautiful family life'.

Simmons also denied she was facing financial difficulty on Twitter, saying “Wow, I put 1 of several properties I own (+ DONT live in) on the market & now apparently my whole life is fallin apart?!" adding, "Rumors, Rumors ...”
