The 37-year-old rapper accidentally confirmed his 17-year-old sister-in-law is dating the 25-year-old rapper, who denied rumours of a romance earlier this week, but hinted he doesn't entirely approve of their relationship.

In a new unedited clip of the 'Only One' hitmaker's pre-recorded interview with New York City radio station Power 105.1's 'The Breakfast Club', obtained by TMZ.com, he said: "I think they in love."

Asked if thought their relationship was inappropriate, he added: "I think that, that's a good question right there.

"You can tell nobody, you can't speak to nobody [about what they can and can't do]."

The comments were removed from the interview when it was broadcast on Thursday (19.02.15).

It was previously thought Kanye had been vague when asked about their relationship status even though he praised Tyga for getting in "early" with the 'Keeping Up with the Kardashians' star, who is his wife Kim Kardashian West's half-sister.

He said: "I think he got in early; I think he was smart. They're closer in age than a lot of relationships I know."

Earlier this week Tyga, who split from Blac Chyna last year, with whom he has two-year-old son, King Cairo, slammed speculation he was dating the teenager, but admitted he thought she was "a beautiful, young woman."

Sources previously suggested the couple wanted to wait until Kylie turns 18 next August before going public.
