Leona Lewis on crutches after falling off her horse in LA

Leona Lewis is on crutches after falling from her horse, it was revealed today.

The former X Factor winner required hospital treatment after suffering suspected torn ligaments in the accident in Los Angeles.

'Leona was riding the day before New Year's Eve and fell off when the horse started galloping too fast,' a source told The Sun.

Back to work: Leona Lewis arrives at LAX Airport in Los Angeles last week, days before suffering a knee injury while horse-riding

Despite the injury she was able to continue with her her New Year celebrations and attended a party at the Bellagio Hotel in Las Vegas.

However, the accident is likely to have marred an enjoyable festive season for the singer who returned to L.A. last week after a down-to-earth Christmas in her home of Hackney, east London.

She had spent a few days relaxing at home with her parents Joe and Maria Lewis and boyfriend Lou Al-Chamaa.

But as the festive season drew to a close, Leona and Lou were spotted arriving back at Los Angeles' LAX Airport on Boxing Day.

The star has spent most of her time in the US since winning the X Factor four years ago.

She has a £1.2million home and has gradually grown to love the City of Angels.

She said earlier this year: 'When I first came here I wasn’t sure if I liked it. It’s taken a while because I love being at home with my family and I miss them when they’re not here.'

The 24-year-old singer is back the US three weeks before the Goldon Globe awards, where her single I See You, the theme tune to hit movie Avatar, is up for Best Original Song.

Lewis was personally requested to record the song by film director James Cameron.

She stole the show at the record-breaking film's recent US premier at Grauman's Chinese Theatre in Los Angeles, wearing a bejewelled silver floor-length gown.
