As far as post-split appearances go, Amy Poehler absolutely nailed it on the red carpet at the Emmys on Sunday evening. The "Parks and Recreation" star wore a sparkly black Stella McCartney gown with a plunging neckline and rocked a surprising piece of jewelry on her ring finger -- but it's not what you think.
"Oh, this is a $2 adjustable ring from my child's toy box," she told Ryan Seacrest. "He told me I should wear it, so I listen to him."
The Emmy's marked Poehler's first red-carpet appearance since announcing her separation from Will Arnett, her husband of nine years, earlier this month. The former couple has two children together -- sons Archie, 3, and Abel, 2.
Poehler was nominated for two awards -- Outstanding Lead Actress in a Comedy and Outstanding Writing for a Comedy Series for her work on "Parks and Recreation." Arnett also received an Emmy nod for his guest role on "30 Rock."
Poehler is not the first celebrity to make a sexy red-carpet debut after a split. Click through the slides below to see six other stars who showed their exes exactly what they were missing post-divorce.
Reese Witherspoon split from ex Ryan Philippe in November 2006. The following awards season, she stood out on the red carpet out in a flirty, yellow Nina Ricci dress at the Golden Globes. Witherspoon remarried agent Jim Toth in March 2011 and the the two are expecting their first child together.
Less than a month after divorcing ex-husband Eric Benet, Halle Berry chose a gold look-at-me pantsuit with leopard lining to present the award for Best Male Performance at the MTV Movie Awards. Talk about letting your hair down, literally.
Though Jennifer Aniston and Brad Pitt's surprising split happened in 2005, tongues still wagged at the 2009 Oscars, when Aniston arrived in a silver Valentino dress with then-beau John Mayer, because it was the first time she had been at a public event at the same time as "Branjelina."
Renee Zellweger and country singer Kenny Chesney wed in May 2005 and annulled their marriage merely months later in September, citing "fraud." She donned a sexy, dramatic Carolina Herrera gown with a high slit for the Golden Globes several months later.
Christina Applegate ended her 4-year marriage to actor Johnathon Schaech in August 2007, citing "irreconcilable differences". That November, she sported a new 'do and an attention-getting bright blue dress for the American Music Awards.
Dita Von Teese filed for divorce from rocker Marilyn Manson in December 2006. The burlesque star departed from her normal rock-n-roll look at Elton John's Oscar party several months later in shimmery, flowy gown. Did she want Manson to view her in a different light?
