Tulisa Contostavlos put on a brave yesterday in Los Angeles amid claims that ex-boyfriend Fazer cheated on her while they were still together.

The X Factor judge wore a cute playsuit teamed with matching green heels and was seen getting out of a car as she made her way to a private house to record her debut solo album in a studio.

Tulisa has spent the past week in L.A. working on her LP and appears to be enjoying herself despite endless reports about her relationship in the media back home.

A model came forward earlier today to allege that she kissed Fazer when they met in a club in London last November.

It is thought that these cheating claims, in addition to a series of rows, caused the couple to split after 18-months of dating.

Check out the photos of Tulisa in the gallery below.
