Sienna Miller looked incredible as she enjoyed a relaxing day at the beach in Ibiza on Monday.

The actress, 41, slipped into a tiny bikini as she soaked up some sun and shielded her eyes with a pair of stylish sunglasses.

She styled her blonde hair with a hint of a wave and went makeup free for the outing, showing off her flawless complexion.

Sienna took a dip in the sea to cool off before wrapping herself in a large grey towel and drying off.

She was joined by a group of friends during her holiday, with the group later heading to restaurant Es Torrent for some food.

The star, who shares a 10-year-old daughter, Marlowe, with her actor ex Tom Sturridge, is currently dating Oli Green, 26.

Sienna and Oli confirmed their romance at a Vanity Fair party back in February 2022 and have been very loved-up ever since.

Earlier this year, the actress told how she had previously spent years investing in a relationship with someone who was 'a bucket with a hole in it of a person'.

She revealed she thought she would be married by her 30s but the relationships she was in during those years didn't work out as she had hoped.

Speaking to British Vogue, Sienna explained: 'I'd invested what felt like the important years in something that was just a bucket with a hole in it of a person. I wasted time. And I felt like time was really my currency.'

She was quick to point out she was not referring to Tom Sturridge, who she dated from 2011 to 2015 and shares daughter Marlowe, ten, with.

The exes have remained on friendly terms and Tom is now in a relationship with Alexa Chung.

Prior to her relationship with Tom, Sienna was engaged to fellow actor Jude Law in 2004 after he popped the question on Christmas Day.
