Kylie Jenner and Tyga arrived together at the American Music Awards in L.A. Sunday night.

The reality star, 18, and older sister Kendall entered the awards show with the rapper in tow before making their way to their seats.

Then, when Jenner took the stage to present rap/hip-hop album winner Nicki Minaj, Tyga was one of the first to stand for the Keeping Up with the Kardashians star.

After attending the award show, the pair were seen holding hands as they made their way to celebrity hotspot The Nice Guy for Justin Bieber’s afterparty along with Hailey Baldwin.

The sisters’ entourage made a quick stop at Kendall’s apartment where Kylie slipped into a tight, white mini-dress with a plunging neckline. Tyga, 26, opted for a blue suit with a white, button-down shirt.

Jenner even posted a paparazzi photo of her walking with Tyga on Monday, captioning the shot “chaos.”

Jenner and Tyga looked to be in good spirits and Jenner even posted a Snapchat of the rapper dancing in a lobby. Another Snapchat showed a fleeting image of Tyga along with the sisters and a few others bobbing to music in a limo.

Sources told PEOPLE Friday that Jenner and Tyga had broken up after a year of dating.

“She’s caught him lying and talking to other girls behind her back before, and this was the last straw,” a Jenner source recently told PEOPLE, adding that Jenner “feels super betrayed and is just so pissed off, damaged and hurt about it” and that she’s “absolutely fuming.”

“She plans to erase him from her memory and act like he never even existed in the first place,” the source said.

However, on Saturday, Jenner kept fans guessing when she posted a Snapchat of a man and a woman lying next to each other with the words “Everyone needs to chill.” The man’s hand bore a strong resemblance to Tyga’s distinctive tattooed arms.

Neither Jenner nor Tyga have publicly commented on their relationship.
