As hard as it is to believe, Kylie Jenner and rapper boyfriend Tyga are reportedly already engaged.

"Kylie accepted Tyga's proposal a few weeks ago and made the announcement to her family," an insider recently told In Touch Weekly, via Radar Online, adding that she wants to get married "as soon as she turns 18" on Aug. 10.

The insider also claimed that the "Keeping Up with the Kardashians" star "can't wait" to walk down the aisle with the "Ayo" rapper, who supposedly got a tattoo of her name on his arm recently.

"She told her friends that Tyga gave her a 'symbolic ring' for now, and she isn't showing anyone until her birthday, when she'll make an official announcement," the insider added. "They're tired of hiding."

Jenner's notorious clan might have had a hard time accepting the couple's secret engagement, as they are reportedly concerned about the teen's relationship with T-Raww.

When the 17-year-old posted a video clip, in which she appears to be mumbling she is "high as f*ck," to her Snapchat account on May 6, many speculated that she was using marijuana. 

HollywoodLife.com recently reported that Kylie's mother Kris and older sister Kendall are upset, believing that she could easily go too far with her partying.  

A source claimed the teenager's behavior has been affected by the "Rack City" rapper, saying that she gets "wild from time to time." 

"Kylie is young, lives in LA and dating a rapper -- so it isn't unusual for someone in her position to be partying the way she does," the source continued. 

Although Jenner took to her Twitter account on May 10 to slam the rumors of drug use, one of her friends revealed to People her family is "worried" that Tyga has a negative influence on her decision-making.

"A lot of Tyga's friends are enablers," the friend said. "That makes her mom the most nervous. She doesn't want Kylie getting off track."
