Kylie Jenner is apparently having a hard time waiting to turn 18 to legally date rapper boyfriend Tyga.

According to HollywoodLife.com, the 17-year-old reality star, who prefers to date older guys, wishes to be the 25-year-old "Rack City" hitmaker's girlfriend once her next birthday arrives on Aug. 10, 2015.

"Kylie's clearly in awe of Tyga and loves being treated like his princess, even though they're just friends," a source revealed. "But she has told her sisters many times, 'I can't wait to be 18. The guys my age are lame and don't know how to treat me like Michael Ray does. He's so fine and a perfect gentleman.' Kylie doesn't even call him Tyga. He's Michael Ray to her."

The latest claim comes after the couple was spotted on a romantic dinner date at Spago restaurant in Beverly Hills, California on Dec. 18, Hollywood Life reported.

"These dates they go on have love written all over them," an eyewitness recalled

. "Take last night for example. They sat side by side and not across from one another. His arm was around her the entire time, and they had a bodyguard with them so that they could enjoy optimal privacy."

Jenner and T-Raww were reportedly getting cozy to the point that they even shared a fork.

"They ordered one serving of pan-seared striped bass and ate off the same plate," the eyewitness continued. "They even used the same fork! He even wiped her mouth with the napkin several times during dinner. He's just too sweet to her."

Meanwhile, TMZ recently reported that Tyga is seeking primary custody of King Cairo, his 2-year-old son with Blac Chyna. He apparently made the decision to file documents after seeing an Instagram video of his ex twerking with fellow model Amber Rose on Dec. 17.
