One week after confirming that her older brother died, Lisa Vanderpump stepped out to support a good cause on Saturday.

Attending the Vanderpump Dog Foundation’s 3rd Annual World Dog Day in West Hollywood, the reality star supported the dog rescue organization she and her husband Ken Todd founded in 2016.

Although she appeared to have skipped out on walking the red carpet, the 57-year-old was photographed smiling alongside singer Leona Lewis at the outdoors event.
