On the rocks? Tyga faces more cheating allegations

Kylie Jenner cut a glamorous figure as she attended the InStyle Golden Globes after-party on Sunday night.

But who did she take along as her plus 1? Not on-off boyfriend Tyga, but sister Kourtney Kardashian.

The pair both looked gorgeous as they posed for pictures at the Beverly Hilton Hotel, where the glittering award ceremony took place.

According to reports, Kylie banned the rapper from attending after he was hit by a fresh round of cheating allegations.

One source claimed that: “Kylie was supposed to bring Tyga as her date last night, but after this last cheating rumour she told him that she needed a break to think things over.”

They added: “Kourtney has taken Kylie under her wing recently because no one in that family knows how to handle a bad news boyfriend more than Kourtney does. She will help her get through this.”

Last week, Tyga was rocked by more bombshell rumours when a Brazilian model claimed he went behind Kylie’s back with her.

Annalu Cardoso, 23, alleged the rapper slept with her while Kylie was “out of the country”.

However, sources have since claimed the pair met while working on a music video in 2014 – and would allegedly meet up while the 18-year-old was away.
