Kristin showed off her growing tummy as she walked the white carpet at the annual event, which Elton holds in West Hollywood to raise money for his Aids Foundation.
The former Hills and Laguna Beach star opted to wear a short dress, meaning she could show off her bronzed pins and black Louboutins. And there wasn't a swollen ankle in sight!
Kristin's nude and black lace maternity dress fitted over her baby bump perfectly and she topped off her look with a stylish up 'do and a tiny black clutch bag. Gorgeous!
The US reality star is expecting her second baby with hubby Jay Cutler and had worn another stunning gown earlier in the evening, during an appearance on TV channel E!.
The white floor-length Alexander McQueen dress was embellished with sparkling beads on the capped sleeves and really showed off Kristin's bump in all its glory!
Sharing a photograph on Instagram, Kristin said: "Had a great time helping countdown to the Oscars on E! I loved my Alexander McQueen dress..felt like a princess."
