Last week, Blac Chyna and Kylie Jenner played the game "Tyga loves me more" on social media, which started when Chyna posted a picture of the Audemars Piguet timepiece Tyga had given her in 2013.

In response, Kylie posted a photo of the watch the "Ayo" rapper gave her, which is nearly identical to Chyna's, with the word, "Currently."

HollywoodLife.com reports that Chyna, 26, fired off yet another shot at Kylie, 17, on Tuesday in a new Instagram selfie as their battle for Tyga, 25, continues. The model didn't write a caption for the picture as it is obvious she's throwing shade by flaunting the diamond-studded watch and her womanly curves.

Chyna, who has a son with the rapper, is reportedly bitter over losing Tyga to the much younger Kylie. If she hoped her antics would throw a wrench in the relationship, it hasn't. Kylie and Tyga were seen over the weekend in Los Angeles having lunch together, reports Inquisitr.

The couple wore color matching outfits, and Kylie drove her new boyfriend around in her pricey Mercedes Benz G-Wagon, reports K Pop Starz.

It was the first sighting of the couple since the "Rack City" rapper confirmed his love for Kylie on Instagram three weeks ago by posting a picture of the reality star along with the caption, "Certain things catch your eye, but only few capture the heart."

Tyga's fans have commented on the inappropriate relationship with Kylie, reminding the singer that she's not 18 until her birthday on Aug. 10.

The age of consent in California is 18, which means it would be illegal for Tyga to engage in sexual intercourse with Kylie, unless they are married, according to Legal Match.

Tyga previously denied he's dating Kylie in an interview with The Breakfast Club, and he insisted that he did not leave his family to be with her, as Amber Rose and others have claimed.

"I just want to get that out of the way. I want to be clear to everybody that I didn't leave my family to be with Kylie. That's ridiculous. You know, me and Chyna, we broke up almost close to a year now, because of the decisions we made. Things in our relationship that weren't going right, so we decided to split to raise a mostly stable kid," he said.

Whether or not the two together, rumors have it Tyga and Kylie are making music together; Kylie's soon-to-be-released single, "Forever Real" is rumored to feature Tyga and Iggy Azalea.
