It’s been over 25 years since I Know What You Did Last Summer was released – and Sarah Michelle Gellar is looking better than ever.
The 47-year-old actress wowed fans while attending the premiere of the reboot of the famous slasher film, looking toned and fresh faced as she posed on the red carpet.
The Hollywood star looked glamorous as she stepped out with husband Freddie Prinze Jr., showing off her toned physique in a strapless Oscar de la Renta butterfly-embroidered mini dress.
The screen star added orange pumps and a matching boxy clutch purse that picked up the orange hue in her fancy frock.
Geller and Prinze, 49, met on the set of 1997’s I Know What You Did Last Summer. They tied the knot with in 2002, and share daughter Charlotte, 14, and son Rocky, 12.
Gellar, whose character was killed off in the original 90s flick, did not return for the new film.
But the actress, who also starred as the titular role on the supernatural drama series Buffy the Vampire Slayer which aired from 1997 until 2003, is set to reprise her role in the upcoming Buffy the Vampire Slayer reboot.
Below, FEMAIL dives into Gellar’s fitness routine and diet as she continues to dazzle with her age-defying looks.

Sarah Michelle Gellar regularly works out at the gym
Gellar does not shy away from a good sweat session at the gym, often seen working out with weights.
In an interview with Parade, she shared recent changes to her exercise routine, explaining she has added lifting to her routine – something she usually avoided.
‘You play these characters and you can’t be shredded, and you have to look a certain way. As you get older, you realize, as a female, you have to focus on bone density,’ she told the publication.
The actress added that she works with a trainer ‘once or twice a week’ for real strength training, and also love Pilates.
In February, celebrity trainer Brach Gould, who is a strength and conditioning coach, shared a video, showing off one of Gellar’s grueling workouts.
Her session consisted of:
- Half Kneeling High Cable Pulls: Works the shoulders and back
- Single Arm Kettle Bell Farmers Walks with High Knee: Improves balance, core, and posture
- Single Arm Dumbbell Lunges: Works the legs while improving balance
- Stability Ball Planks: Engages core muscles for sexy abs and stability
- Plate Weighed Side Steps: Improves hip mobility
- Side-to-side Medicine Ball Slams: Engages all the important muscles
- Assault Bike to end

‘I’ve been working with Sarah for over six months now and all I can say is how impressive her progress has been!’ the personal trainer captioned a short clip shared online.
He added: ‘She’s become stronger, fitter and more mobile by just sticking to a program and working on the fundamentals.’
Gellar has also said in the past she doesn’t let a trip away from home get in the way of getting her workout in.
‘When I’m travelling, I always pack my resistance bands,’ she told Women’s Health.
‘There’s so much you can do with them,’ she gushed. ‘I had my trainer make a hotel exercise program for me on days when I just can’t make it out to the gym.’
She added: ‘My bands are key, but I’ll often use hotel hand towels as sliders, too.’
The actress makes her own food to take with her on set
Gellar has previously stated she enjoys making her own food, and follows a balanced meal plan.
The mom-of-two told Women’s Health she always makes sure to look at food ‘holistically.’
‘It’s not just about the food I ate today, but the food I ate this week or this month. Because as you get older, you realize it’s about the whole picture,’ she shared.
Gellar is known for bringing her own food most places she goes, including to set and while traveling.
‘I bring my own food to set a lot of the time so I can eat the food I want to eat when I need it, versus when they break for lunch,’ she explained. ‘We don’t get the ability to be like, “Oh I’m hungry now, let me eat.”

The actress added that she’s a ‘dedicated meal planner.’
‘Everyone at work makes fun of me because I’m always walking around with a lunch bag,’ she laughed. ‘Even on the airplane yesterday, everyone was laughing at me because I had to get extra ice for my lunchbox.’
The Buffy actress added she ‘always’ makes sure to eat a balanced meal.
‘You need your protein, your carbohydrates. You need to figure out what gives you energy and what works for you,’ she continued. ‘I bring my lunchbox on the airplane so I can eat when I need to.’
Gellar is also a big fan of meal prepping, and says she uses the app My Fitness Pal to help her tick all of her nutrition goals, sharing a regular ‘day on her plate’ to the food-tracking apps blog.
A typical breakfast is usually overnight oats with almond milk, chia seeds, blueberries, and almonds, and will male a salad, wrap, a Buddha bowl with brown rice, edamame, snap peas, chicken breast, and a soy-vinegar dressing for lunch.
