Just a few weeks after rumours emerged that Blac Chyna had cheated on her fiance Tyga, the couple have split.

According to TMZ, the Young Money rapper, 24, is the one who instigated the break-up with his video model girlfriend.

It's unclear why he called time on their three year relationship but an insider told the online publication that while Tyga is keen to move on, Chyna is in denial, refusing to acknowledge the breakup and that some of her stuff is still at the house.

The family mansion in Calabasas, California was purchased by the rap-star for $6.5m (£3.9m) back in 2012 on the same day their son, King Cairo, was born.

The separation comes after the former stripper was recently caught up in a messy online feud with a woman who accused her of cheating on Tyga. Chrissy V, who is the girlfriend of another rapper known as Fat Trel, claimed that Chyna cheated on Tyga with Trel at the Calabasas mansion while her baby was asleep in the next room.

The mother of one was quick to respond to the rumours, writing: "Stop with the lies!!!..I never used to date another rapper named Fat Trel Ever so dead all this Sh*t now. A fool would believe everything they see or hear! My love and loyalty has been with Ty and King.. so miss me with that rap sh*t!!!!?".

Despite the 26-year-old professing her loyalty and hoping for a reconciliation, that looks unlikely to happen anytime soon because the Rack City rapper is reportedly adamant the break up is for good.

Chyna, who is best friends with Kim Kardashian and is often pictured out around Beverly Hills with the reality star, will undoubtedly be seeking the brunette beauty's advice as she has experienced a few difficult break-ups herself.

Meanwhile, Tyga hosted two pool parties at their home in the last few weeks (including one for reality star Kylie Jenner's birthday) but allegedly his former fiance wasn't invited to either.

The couple have been together since 2011 and got engaged in December of 2012. Their son, King Cairo, turns two in October.
