Tristan Thompson was seen sneaking two women into a bedroom at a late night 'singles' party on Valentine's Day, DailyMailTV can reveal.
The 27-year-old basketball star partied with the women at a luxury mansion in Woodland Hills, Los Angeles, last Thursday.
According to a partygoer who spoke exclusively to DailyMailTV, the 6ft 9in Cleveland Cavalier was 'all over' the pair of beauties described as a Latina with brown hair and a Middle Eastern woman both in their early 20s before he vanished into a room with them for 35 minutes.
Earlier in the day, Khloe, 34, posted a photo on Instagram of a huge floral arrangement of red and pink roses that Thompson had apparently sent her and daughter True as a Valentine's gift.
The revelation about Thompson's Valentine's Day tryst with the two women comes three days before he was reportedly seen making out with Kylie Jenner's best friend Jordyn Woods, 21, at a house party on Sunday night.

The NBA star, who is reportedly no longer with baby mama Khloe Kardashian, partied with the women at a luxury mansion in Los Angeles last Thursday
The party was held at the $3.2million 5,800 sq ft two-story mansion belonging to Cavs star Jordan Clarkson. The source said Clarkson had cleared out all the furniture to create a club vibe and caterers were dishing out food
Their split comes 10 months after DailyMail.com first caught Tristan with another woman right before Khloe gave birth to their daughter
When Khloe found out, she broke off their two-year relationship on Monday, according to TMZ.
DailyMailTV contacted Thompson's representative for comment but did not receive a response back by the time of publication.
The eyewitness at the Valentine's Day party, who asked that she not be identified, told DailyMailTV: 'It was a Valentine's Day party for singles, mostly ladies, super exclusive, guest list only.
'It was at the home of Jordan Clarkson who plays for the Cavs and there were quite a few Cavs players there, but it was mostly girls.
'They had red heart balloons everywhere on the ceiling and happy V'Day signs, a DJ, hookahs everywhere, club seats.
'Then at around 11.30pm Tristan comes in, he's smiling, very playful, very happy, and immediately he's dancing with his teammates and some girls.
'Me and my friends were like, "why's he not with Khloe and his baby on Valentine's Day?".
'Then I saw him drinking and knocking back shots at the bar and he was flirting and exchanging numbers with girls who came up to him - he certainly didn't look like he was with Khloe any more.'
The source said they saw Tristan partying with a handful of different girls during the course of the night.
'He was dancing, flirting, touching, grabbing butts, that kind of thing,' the source said.
'As the night went on I saw Tristan dancing and grinding with two women in particular and he was in good spirits, he seemed very happy.'
The partygoer said Tristan and Cav teammate Clarkson were with a group of three girls at one point who were smoking on a hookah pipe.
The group then disappeared into a back room, behind the DJ booth.
The source believes it was some kind of office off the main living area and claims the door was locked behind them.
Tristan sneaking off to a bedroom with the women came hours after Khloe, 34, cuddled up to her 10-month-old little girl True in a series of snaps shared to her Instagram (pictured)
'He was acting like all the single guys in there,' the source said. 'Not like a guy who sent Khloe flowers earlier in the day.' Khloe posted this photo showing off a massive heart-shaped red and pink rose floral arrangement from Tristan. Khloe captioned the post: 'Daddy and baby True'
But within hours of the post rumors began to emerge that all wasn't good in the relationship. 'They are done — for good,' an insider told Radar Online of the duo who started dating in 2016. Pictured: Khloe with True on Saturday
At around 1.30am Tristan and the group re-emerged, the source told DailyMailTV.
'They carried on partying, I'm thinking they're pretty drunk by now, there was a lot of drinking, it was unlimited liquor,' the source said.
'Tristan was dancing with the girls, pretty much behaving like a single guy.
'I remember some people going up to him saying, "Hey Tristan how you doin', where's Khloe?" He pretty much laughed and ignored the question.
'It was a singles party, all the sexy, pretty ladies and the NBA players, that was the vibe. I'd say it was 7-1 girls to guys.'
According to the source, among the female guests were Love & Hip Hop's Miss Nikki Baby and Malaysia Pargo star of Basketball Wives LA.
The home is a $3.2million 5,800 sq ft two-story traditional style mansion which Cavs star Clarkson bought in February last year.
The house features folding glass doors, a saltwater swimming pool and a trellis-topped barbecue pavilion. It also boasts a double-island kitchen, a home theater, an office, five bedrooms and six bathrooms.
A butler’s pantry connects the kitchen and dining room, which has a glass-enclosed wine room.
Clarkson was traded by the Lakers to the Cavs in February in a deal that also included Larry Nance Jr. and Isaiah Thomas.
Clarkson, 26, was rumored to be dating Khloe's sister Kendall Jenner in 2016, as the two were frequently pictured together and she sat courtside for his games in LA.
The source said Clarkson had cleared out all the furniture to create a club vibe and caterers were dishing out food.
