Isla Fisher looked incredible as she slipped into a plunging black swimsuit for a sun-soaked day by the pool.
The Confessions of a Shopaholic star, who celebrated her 50th birthday earlier this year, showed off her toned physique in the chic one-piece as she relaxed on a lounger with friends.
Sharing a series of images from the outing on Instagram, Isla appeared in high spirits as she sat cross-legged beside the pool, with her red hair swept into a relaxed updo.

In another close-up selfie, a makeup-free Isla reclined on a towel wearing a turquoise baseball cap emblazoned with the words "Do not disturb."
The images offered another glimpse at the star's enviably toned physique at 50, which she maintains with a varied approach to exercise rather than relying on one particular workout.

Isla's fitness routine combines cardiovascular exercise with a strong focus on flexibility and the mind-body connection.
The actress is reportedly a keen hiker and has frequently taken to the trails of the Hollywood Hills, while yoga has long been an important part of her routine.

The low-impact practice can help build strength and flexibility, while offering a markedly different type of movement from the cardio-based workouts Isla also incorporates into her regime.
Isla Fisher's workouts
Isla has also been a fan of the Tracy Anderson Method, the celebrity-loved workout created by trainer Tracy Anderson.
The method combines dance cardio with muscular structure work and has attracted a long list of famous devotees over the years.
Tracy previously spoke exclusively to HELLO! about the importance of taking a balanced approach to exercise in midlife, particularly amid the growing conversation surrounding maintaining muscle mass after 40.
"I think it's great that we're having more conversations about menopause but I'm also seeing the fall-out from doctors scaring women into thinking they suddenly need to start flinging ropes and lifting heavy weights," she explained.
© Instagram"You only actually lose between 3 and 8% muscle mass per decade after the age of 40 which isn't much so you need to outrun rather than overcorrect that loss by investing in a range of movements (running isn't going to cut it) and adding incremental weights without injuring yourself."
Tracy believes variety and balance are particularly important as women move through midlife, rather than relying on a single form of exercise.
"For me, step aerobics and Pilates weren't transformative enough and it wasn't until I realised that balance is continuous that I started studying the movements that could take any woman from any genetic background and turn them into their most balanced self," she told HELLO!.
"At the end of the day most women just want to get into proportion and you can't do that by relying on one thing like running."
