Alyson Hannigan Celebrates 20-Lb Weight Loss After 'DWTS’ Transformation

Alyson Hannigan was not crowned the newest champion of Dancing With the Stars, but she’s grateful for all she’s gained — and the weight she’s lost — from her experience in the ballroom.

The How I Met Your Mother star, 49, shared side-by-side snaps to Instagram of her pre-season promo picture and a shot from the DWTS finale on Tuesday, December 5. In both photos, Hannigan sported a silver fringe dress.

“The before and after says it all,” Hannigan wrote on Saturday, December 9. “I lost 20 pounds of both weight and emotional baggage during my time on @dancingwiththestars.”

In her caption, Hannigan went on to credit her partner, professional dancer Sasha Farber, for aiding her in her journey. (The pair finished in fifth place during the season 32 finale after performing a salsa redemption dance to “Get on Your Feet” by Gloria Estefan and freestyle to “Enchanted (Taylor’s Version)” by Taylor Swift and “Papi” by Jennifer Lopez. Xochitl Gomez and Val Chmerkovskiy took first place.)
