On Saturday the singer invited a slew of her famous pals to a private party benefitting the Hopefield Animal Sanctuary
, a safe haven for abused and neglected animals in Brentwood, England.
Donations are still coming in, but so far Lewis and her guests raised more than $30,000 at the soiree (organized by party planner Marley Majcher), which featured performances by Lewis herself, Natasha Bedingfield and Glee
star Matthew Morrison.
Lewis was grateful that her animal-loving friends showed their support by stepping out for the fund-raiser. "Thank you so much @matt_morrison
for coming and having a little sing song with me in aid of hopefield_uk animal sanctuary! big hugs," she Tweeted
