Vince Vaughn, sipping on Grey Goose and soda while chatting with Dallas Mavericks owner Mark Cuban at a VIP table of Pure Nightclub at Caesars Palace in Las Vegas. The unshaven actor shook hands with fellow revelers as he enjoyed a mellow evening.
Courtney Love, partying with pal Joaquin Phoenix at L.A.'s Hyde Lounge. The newly svelte rocker, who wore a skin-tight black minidress and knee-high boots, jumped around from table to table, chatting with friends and made multiple trips to the venue's smoking patio.
Heidi Klum, unveiling the new Victoria's Secret Extreme Plunge bra and debuting their "What's Sexy?" list at the VS store at Caesars Palace's Forum Shops. The supermodel told us that she's making sure her children – daughter Leni, who turns 3 on May 4, 19-month-old Henry and 4-month-old Johan – are bilingual. "I read a lot of German books to them. I want them to speak their mom's language," she said. "I speak mostly German to them and there are tons of German movies that we watch."
