Australian actress Rebel Wilson stepped out in London with pal Matt Lucas showing off her impressive 4 and a half stone weight loss.

The 41-year-old comedian wore leather look leggings as she strolled through the capital on Wednesday looking amazing.

She even took in a bike ride with her old pal Brit comedy actor Matt Lucas, whom she has remained friends with since being in 2011 hit comedy film ‘Bridesmaids’.

Unfortunately she did fall off her rental bike suffering some minor bruising after colliding with a group of dog walkers.

Rebel’s drastic weight loss has been attributed to a new healthy diet and exercise regime which she posts regularly about on her social media.
