AceShowbiz - Performing Frank Sinatra's "The Lady is a Tramp," Kate Hudson and Martin Short showcased their musical prowess, with Short tweaking the lyrics to pay tribute to Hudson. The pair also performed a few solo songs, including tracks from Hudson's debut album, "Glorious."

Hudson, who rose to fame with her Oscar-nominated role in "Almost Famous," has always had a passion for music. After releasing her album in May, she recently performed her songs live for the first time.

"Music has always been my first love," Hudson said. "I've always been fearless in my decisions, but this was the one thing I was so afraid of."

Hawn's charity event also honored the iconic Hollywood love story between Hawn and Kurt Russell. Russell shared his secret to a successful union: "She is always my priority." The couple has a blended family of six, including Hudson and her daughter, Kate.

The Love-In Gala attracted a slew of celebrities, including Demi Moore and Fergie. Hudson looked dazzling in a floor-length black fringe gown and matching silver heels, while Hawn celebrated her foundation's milestone in a sparkling gold dress.

Hawn's foundation and MindUp have been providing mental fitness tools for students, educators, and families for 20 years. The program equips participants with skills to face challenges with optimism and resilience.
