Topher Grace, Sunny Mabrey, Abigail Spencer and others celebrate 160 years of Bally's Swiss Heritage (and benefit a worthy children's cause at the same time); Jennifer Love Hewitt, Melissa Joan Hart and a full complement of Bravo stars including a special selection of both Kardashians and Real Housewives strap on their ice skates for a Disney On Ice skating party at LA Live; Common takes the stage at a progressive design showroom; and Samantha Ronson DJ's Rachel Zoe's holiday party—for all the details, check out this especially design-oriented edition of Last Night's Parties.
