It has recently been reported that Tyga is already calling his rumored girlfriend Kylie Jenner's mother, Kris Jenner, his Mom.

Things are seemingly getting pretty serious between the young couple, as the Young Money Cash Money Billionaires emcee is being considered part of the notorious Kardashian/Jenner clan, according to Hollywood Life.

For instance, the matriarch just turned 59-years-old on Wednesday, and the "Rack City" hitmaker apparently gave her a heartfelt handwritten birthday card. Kanye West and French Montana -- the husband and the reported reunited boyfriend of the 17-year-old reality star's half-sisters Kim and Khloé Kardashian, respectively -- did the same.

"It was on a simple white piece of paper with no lines," a source said of the special letter Kris received. "They each had handwritten a few kind words, thanking her for the influence and love she's given each of them in the course of their lives."

Kris was also reportedly touched when the rapper trio referred to her as their "Moms."

"It bought her to tears because each one of them began the letter with the words, 'Dear Moms,'" the source said. "That moved her in such a way because she said, 'can you believe they took time to plan something for little old me that's so touching with all that's going on in their lives. This made my day.'"

The source then claimed that Kris is happy with her daughters' significant others, even including T-Raww.

"She also said, 'my girls are so lucky to have these men in their lives. They're just marvelous,'" the source continued. "Kanye 'can't do any wrong' and 'his words are truly profound.' She said, 'French is so charming and he could really make Khloé happy.' And she adores Tyga and said, 'he's so sweet. What a loving young man he's growing up to be.'"
