Rumer Willis looked incredible as she put on a showstopping performance at the annual amfAR gala in Venice Sunday.

The influencer, 36, who revealed she had split from her partner Derek Richard Thomas 16 months after the birth of their daughter, Louetta, walked the arrivals line in a stunning chocolate satin and chiffon gown.

The frock featured a plunging neckline and draping that accentuated her curves, while a flowing wrap covered Willis' arms and created a train-like affect as she strolled along the carpet.

Once inside the event, Rumor performed for guests including Eva Longoria, Kate Beckinsale and Lucien Laviscount.

As well as Rumer, former Destiny's Child member Kelly Rowland also performed at the event.

While there, the singer rubbed shoulders with others, including Global Impact Award winner Antonio Banderas and his girlfriend Nicole Kimpel.

The annual gala raises funds for AIDS research and HIV prevention.

Since 1985, amfAR has raised nearly $900 million in support of its programs and has awarded more than 3,800 grants to research teams worldwide.

The late Elizabeth Taylor was one of the founders of what was then called the American Foundation for AIDS Research in 1985, at the height of the AIDS crisis, and helped bring attention to the need for government research and treatment for the deadly disease which, in the US, affected mostly gay men.

Taylor testified before Congress in 1987 to plead for medical help to treat patients, and helped convince lawmakers to pass the Comprehensive AIDS Resource Emergency (CARE) Act in 1990. 

In 1993 Taylor received the Jean Hersholt Humanitarian Award from the Oscars for her work.

Willis will headline the upcoming western Broken Trail, as a woman whose husband's murdered is orchestrated by a crooked colonel, played by Jeff Fahey.

With the help of a former Pinkerton agent played by Gbenga Akinnagbe, they plan their revenge against the dastardly colonel. 

The movie was listed as being in post-production on IMDB. No release date has been announced.
