Jennifer Tilly, 65, stuns in plunging purple lace gown with sheer sleeves as she steals the spotlight at Family Guy 25th Anniversary Celebration during PaleyFest

Jennifer Tilly showed off her ageless beauty at the Family Guy 25th Anniversary Celebration in Los Angeles on Friday.

The 65-year-old Oscar-nominated actress – who portrays Bonnie Swanson in Family Guy – stunned in a purple lace dress as she arrived at the PaleyFest gala celebrating the animated comedy.

The beauty wowed with her glamorous movie star look, wearing a plunging dress with sheer black sleeves and accessorizing with a statement red fabric belt to match her lipstick.

She added a designer clutch and high heels to complete the fashionable ensemble, as she kept her brunette locks aside.

Jennifer was joined by the all-star cast of the Seth MacFarlane sitcom, including Mila Kunis, Seth Green, Alex Borstein and Patrick Warburton.

A few years after her breakout roles as Violet in 1996’s Bound and Tiffany in 1998’s Bride of Chucky, Jennifer landed the role of Bonnie in Family Guy.

Bonnie is the wife of Joe Swanson (Patrick Warburton), a character who appears in more than 80 episodes from seasons 1 to 21.

Meanwhile, Jennifer is back as Tiffany in the second half of the third season of the Child’s Play spin-off television show Chucky.

With the killer doll Chucky coming to the White House this past season, Jennifer was asked what her character Tiffany would be doing in the president’s palatial palace.

“If Tiffany was in the White House, she would redecorate it,” the actress said Collider. I mean, she doesn’t like tasteful neutrals. I think she would do a lot of gothic-inspired decor, like red velvet walls and black leather couches and things like that, like jeweled chandeliers.

‘Tiffany likes everything over-the-top. Of course, some rooms will need to be redecorated to match your outfits. So I think that will be her biggest concern: redecorating the White House.”

She hilariously added that there would be a special room for killer doll couple Tiffany and Chucky.

“You know how Candy Spelling has a room where she can wrap presents? Well, Tiffany and Chucky are going to have to have a room in the White House where they put the bodies,” she joked.

“So there’ll be some kind of little parachute, you pick up the parachute and the body goes down to the basement, maybe to fall into a vat of acid or something.

“But you have to have a place to store the body. It is very important.’

Jennifer’s association with the role dates back to 1998 when she played the titular character in Bride of Chucky, the fourth installment in the Child’s Play franchise.

She reprized her role for the next three films in the series: Seed of Chucky, Curse of Chucky and Cult of Chucky.
