The on-off couple were thought to have rekindled their romance after Chris and Rihanna called time on their turbulent relationship earlier this year, but now things with Karrueche appear to be pretty official again after she accompanied Chris to the BET Awards yesterday evening (30 June).
The petite Vietnamese model made no secret of the fact that she attended the award ceremony in LA to support Chris - who was performing on the night - and even uploaded an intimate picture of them together before the show began, along with the caption: "My baby. Good luck today."
Perhaps Karrueche was making a point that the R&B singer is now hers once more, after she appeared to receive a number of subtle digs online from Rihanna when she and Chris began dating again at the end of last year.
The sweet snap shows 24-year-old Chris wearing a plain white T-shirt and leaning against Karrueche, while she appears to be more dressed up and places her arm around him.
However, this isn't the first time that Karrueche and Chris have been caught sharing a tender moment in a candid photo.
Last month, a friend of Chris' posted a picture of the couple looking pretty loved up and cuddling one another at Chris' Hollywood home. The caption read: "No friendship without love!"
On top of that, the two stars have been spotted hanging out on a number of other occasions.
Not only was Karrueche seen cheering Chris on backstage in New Jersey for the Hot 97 Summer Jam concert, she was also riding in the passenger seat when the award-winning pop star allegedly rear-ended a car in a traffic incident in LA last month.
Meanwhile, Rihanna has been busying herself on her 'Diamonds' world tour and was pictured head-to-toe in Adidas last week while out and about in Germany.
With RiRi on the road, it looks like Chris has found someone else to keep him company. We wonder if this time he and Karrueche are for keeps!
What do you think of Chris reuniting with Karrueche? Let us know below.
