French reality star Nabilla Benattia has been arrested on suspicion of stabbing her boyfriend.

Nabilla, who rose to fame on Les Anges de la Téléréalité (The Reality Angels), is suspected of causing serious injuries to boyfriend Thomas Vergara in the early hours of Friday morning.

Authorities were alerted after the staff of a Paris hotel reported a “major argument with lots of screaming” from a room upstairs.

Vergara was then discovered with stab wounds to his chest and throat, and was rushed to the Georges Pompidou hospital, where he remains in a serious condition. Benattia was also treated for shock.

Police went on to arrest the 22-year-old reality star on suspicion of attacking her boyfriend.

According to reports, Benattia has denied the charge, claiming that Vergara was attacked by three men outside the hotel. The hotel staff, however, have no CCTV evidence to back up the claim.

Benattia is being held by police and will be formally questioned as part of an “attempted homicide” investigation later today.
