Sienna Miller embodies old school chic as she shares three-word verdict on Oasis gig

Sienna Miller looked effortlessly cool as she attended night two of the Oasis reunion concert at Cardiff's Principality Stadium. Like many tens of thousands of people, Sienna was quick to nab tickets to the tour after Liam and Noel Gallagher shocked fans with a reunion announcement in August last year.

The band finally returned to the stage on Friday night for their first performance together in 16 years. Sienna, who attended both nights of the Cardiff concerts, said it was the "greatest show I've ever seen" as she shared her thoughts on the emotional night, which had Liam and Noel performing all their biggest hits.

When asked by The Mirror what she thought of the concert, she joked: "It was alright," before revealing she was there for both Cardiff gigs. "It's the greatest show I've ever seen. The love and the nostalgia and the joy, it's like saving the world."

The Extrapolations actress, 43, rocked a patterned black-and-white long-sleeved short for the biblical event and accessorised with thin-framed sunglasses. She made her look chic by tousling her blonde locks.

She joined Doctor Who's Matt Smith, who was also at both events, for the concert. Other big names at the gig included makeup mogul Charlotte Tilbury, Noel Gallagher's girlfriend Sally Mash and more.

Last year, Sienna opened up about ageism as she admitted she initially had reservations about dating a younger man.

She shared that it didn't take long for her to become smitten with Oli Green after they met at a Halloween bash.

In an interview, Sienna revealed that she wasn't planning on taking things "seriously," but unexpectedly found herself falling in love.

Initially, Sienna was conflicted about the age difference, stating that it just sort of happened. She elaborated: "I wasn't like, 'I'm gonna get a younger boyfriend.' It was more, 'F---! Why are you young? That's so annoying.'".

Looking back, however, Sienna believes everything worked out for the best. In a chat with Harper's Bazaar, she praised Oli for his maturity, describing him as "very wise and well-adjusted."

She attributed his mature outlook to generational differences, noting that Oli belongs to a "generation of men respect women."

She continued: "It's interesting, being older now, and having been raised in that moment, learning from people who are younger about how clear they are in their boundaries, having that self-assuredness and self-advocacy, having 'no' in the repertoire in a way that we just weren't encouraged to have."

Meanwhile, Oasis is next returning to the stage for five dates in Manchester, starting from July 11, before heading to London for another five dates.

They will also be heading to Dublin, Toronto, Chicago, New Jersey, Los Angeles, Mexico City, and will performing a few more London dates in September.

In October and November, Oasis will also be in South Korea, Japan, Australia, Argentina, Chile and Brazil.
