There was no question that Khloe Kardashian was in the mood for celebrating her on-again boyfriend French Montana's 30th birthday on Sunday night.
However, not only did the reality star reveal her feelings, she also revealed a little too much skin, seemingly unaware of just how see-through her sheer dress was under the flashbulbs as she went without a bra.
The 30-year-old suffered the wardrobe malfunction as she attended the star-studded 30th Birthday Party Powered by CIROC Pineapple in Los Angeles.
Khloe revealed a lot of leg in the semi-sheer midnight blue dress, however it was unclear if she realised that the top half of the dress was quite so see-through.
It appeared to be a fairly formal affair, with her beau French looking dapper in a white suit jacket and red tie.
Meanwhile, Khloe's sister Kim posed with momager Kris, 59, and little sister Kylie Jenner, 17, who appeared to be dressed rather inappropriately for the bash.
It is understandable that Kim appeared not to be in party mood at the event, having just got back from her extremely hectic trip to London.
Meanwhile, in San Francisco, Kanye West was seen on daddy duty as he pushed their daughter North around in a stroller.
It appears that all is back on between birthday boy French and Khloé, show dated for seven months before splitting in September.
Earlier that day, Khloe, who herself turned 30 on June 27 - for which her then-beau gifted her with a white Jeep Wrangler worth an estimated $49,000 - posted a sweet flashback Instagram photo wishing him a happy birthday as she revealed she would be celebrating with him later that night.
In the photo, a mostly silhouetted Khloe drapes herself all over French as they stand together on a beach, the waves lapping at the shore, the sun setting behind them beautifully.
While the Keeping Up With The Kardashians star appears to be wearing a black knee-length dress as she stands on the tiptoes of one foot, she has her other leg raised up in the air behind her, one hand clutching her man's shoulder as the other reaches around his waist.
Her head is tilted down as she appears to be kissing him on the back of his shoulder, her long blonde tresses styled in beachy waves which are tumbling down around her face.
Her rapper beau appears to be gazing at his lady love, his head turned to the side as he stands close beside her, clad in black calf-length shorts, a plain white T-shirt and black shower slide sandals, with a silver pendant around his neck.
While he's holding onto a drink container in the crook of one arm, his other hand appears to be grabbing his crotch somewhat suggestively.
While the pair are yet to officially confirm that they are back together after going their separate ways in early September following a very passionate few months together, her caption certainly indicated as much.
'Happy birthday baby boy! In only a short amount of time we have created timeless memories. Happy birthday to a man who genuinely lives life to its fullest,' she gushed.
The trials and tribulations of their love has been playing out on Khloe's new spin-off show, Kourtney & Khloé Take The Hamptons.
She also added rather tellingly: 'I can't wait to celebrate life with you tonight! You deserve it!!'
Khloe has spent the past few days in England with sister Kim Kardashian, where they were the guests of honour at the Hairfinity UK launch party.
However, the pair jetted back to LA on Sunday afternoon - timing it perfectly to be able to party with her man later that evening.
