Kylie Jenner doesn't want her fans "to get too invested" in her relationship with Tyga.
The 18-year-old reality TV star, who previously had a low-key romance with actor Jaden Smith, has been dating the 25-year-old rapper since August 2014, admits she tries not to talk about him very often in case they break up.
She said: "I don't think I will ever be super-public about my relationships.
"I do think that if you let people in too deep, it gets hard - your fans get too invested, and then they know when you break up and make up. I don't want people to know every time we fight or break up, so I'd rather keep some things private."
Despite finding fame as a child on 'Keeping Up with the Kardashians,' Kylie says she rarely lets cameras document her doing real "teenage stuff."
She told the December issue of ELLE Canada magazine: "When I first started on ['KUWTK'], I didn't want anyone to know who my friends were and you never saw any of them onscreen with me. I always wanted to keep my family life on the show, and when it came to me hanging out with my friends and doing, you know, teenage stuff, I wanted to keep that private - and I still do."
