Four-time Major champion Naomi Osaka attended a concert by South Korean boy-band BTS - Bangtan Sonyeondan - at the Sofi Stadium in Los Angeles on Wednesday. Osaka posted a couple of Instagram stories from the event, confirming her presence.The Japanese superstar has long been a fan of the boy band, often openly admitting her love for them on social media. On this occasion, Osaka made it a point to travel to California to watch them live in action.One of the stories posted by Naomi OsakaNaomi Osaka in awe of BTS' performanceNaomi Osaka has been taking time off from tennis since losing in the third round of the US Open. She went on a holiday to Greece a few weeks ago and now seems to be in L.A., where she attended BTS' concert.With the Australian Open less than seven weeks away, it remains to be seen if and when Osaka resumes tennis training in full swing. The 24-year-old has resumed racket training around three weeks ago, going by her Instagram posts, but she will undoubtedly look to up the ante as the Australian Open inches closer.Meanwhile, coming back to the BTS concert, Naomi Osaka wasn't the only famous face in the stadium (barring members of BTS); American rapper Megan Thee Stallion joined BTS, performing her verse of their hit duet 'Butter' together on stage.yati misses bts@yatisanghvii'm screaming shaking crying throwing up y'all i can't breathe i can't function we got megtan i repeat WE GOT MEGTAN #PTD_ON_STAGE_LA04:50 AM · Nov 29, 20217627i'm screaming shaking crying throwing up y'all i can't breathe i can't function we got megtan i repeat WE GOT MEGTAN #PTD_ON_STAGE_LA https://t.co/KP9d45lyWYSinger Halsey was captured dancing to the hit tracks belted out by BTS.별@ttokitae211201 Halsey Instagram story #방탄소년단 @BTS_twt.06:23 AM · Dec 2, 202178513350211201 Halsey Instagram story #방탄소년단 @BTS_twt. https://t.co/UVKvNSyFdYNaomi Osaka and Halsey are big fans of BTSNaomi Osaka is a self-confessed fan of BTS, having once famously run an Instagram fan account known as ‘free hobi’s forehead.’ The name refers to BTS rapper J-Hope, who usually sports hairstyles with bangs covering his forehead.
