Bikini wars! Karrueche Tran posts sexy swimwear snap at the same time as Rihanna... as Chris Brown stays in rehad

After their moist, confronting tongue-to-tongue selfie on New Years Day, it seems Karrueche Tran has still got Chris Brown's heart.

However, when both she and Rihanna uploaded sexy bikini snaps to Instagram within mere minutes of one another on Saturday, it seemed plausible that the pair's subtle jousting for the troubled singer's attention may still be alive and kicking.

The thinly veiled social media competition came just one day after Karrueche enjoyed a boisterous girls night out at Hollywood's Laugh Factory comedy venue with a gaggle of her famous girlfriends, including Christina Milian, Amber Rose and Priscilla Ono... while Chris presumably remained in his rehab facility.

Showing off for anyone in particular? While her boyfriend Chris Brown is presumably still in rehab, Karrueche Tran posted a bikini shot just minutes after Rihanna posted one of her own on Saturday

Competing interests? Chris Brown's ex-girlfriend Rihanna happened to post a saucy bathing suit photo on the same day that his new girlfriend did the same

In Karrueche's upload, she poses seductively in an orange bikini with the straps pulled down, with a thin collection of gold chains drawing attention to her flawless neckline.

Throwing the camera a casually saucy gaze, the model makes sure to remind her boyfriend just what he's got on his hands.

Meanwhile, within the same hour, Rihanna uploaded sexy bikini photos - captioned as being taken in Brazil - in which she too looks as delectable as can be in minimal clothing.

Cheeky! In another shot Rihanna pulled her bikini out flashing a bit more than expected

  

From the front, Rihanna shows off ample cleavage and in another shot taken from behind, a G-string design shows off her pert derriere for all to see, as she stands in what looks to be a mystical waterfall.

Whether or not the ladies were competing for any sort of attention from the Mechanical Dummy singer is uncertain, but if nothing else it's an eerie coincidence.

Perhaps Karrueche was soaking up the sun as a way to recover from the night before.

The pretty model spent the night out and about with a troupe of other famous ladies, taking in the best of LA's comedy at the world famous Laugh Factory.

The group of girls seemed to be having a whale of a time watching their comedian friend Amy Schumer perform, snuggling together in their sexy, revealing outfits to pose for happy snaps.

Karrueche was adorable in a white flowing strapless dress, which featured billowing sleeves and gave her somewhat of a prairie girl aesthetic.

And they weren't just silent spectators, either.

As evidenced in an Instagram video, Christina Milian and Amber Rose took the stage at one point to introduce their comedian friend Amy Schumer.

Karrueche has been standing by her man Chris Brown while he undergoes his stint in rehab, after a judge revoked his probation during a probation violation hearing due to his arrest in Washington for allegedly punching a man's face.

As part of his punishment, Brown must complete 1,000 hours of community labor in addition to serving out his three-month stint in rehab.
