Past (and possibly future) judge of The Voice; mother to 5-year-old Max; smokin' hot, red-carpet sex symbol.

Christina Aguilera showed off her slimmer figure at Tuesday's New York gala to honor Time's 100 Most Influential People, a list on which Aguilera appears alongside Jimmy Kimmel, Jimmy Fallon, Jennifer Lawrence and power couple Beyonce and Jay-Z, among others.

Who else made Time's 100 Most Influential People list?

Aguilera wore a black, low-cut Victoria Beckham dress, with Christian Louboutin shoes and Lorraine Schwartz jewels, reports.

"I'm very honored to be part of the #Time100 list and for the wonderful words from Celine Dion. Thank you!" Aguilera wrote on Twitter on Monday. Dion praised Aguilera in the magazine.

While Aguilera took on a fuller figure in the past and was working on her newest record, Lotus — she now appears to be back in superstar shape. We first saw the beginnings of her revamped figure in March at The Voice's fourth season premiere event, during which she told reporters that she was undecided about coming back.
