India, May 25 -- P op icon Britney Spears is making headlines after she admitted to drinking and smoking mid-flight during a private jet trip from Cabo San Lucas to Los Angeles on May 22. The 43-year-old shared her version of events on Instagram, revealing it was her first time trying vodka - and that it made her feel "so smart". In a now-viral post, she wrote, "Confession: it was my first time drinking VODKA!!! I swear I felt so SMART!!! I felt so clear and said I want a cigarette so bad!!! My friend lit it for me, so I was like, OH, so this is a plane where you can smoke!!!" However, her actions reportedly alarmed flight attendants, who quickly intervened and asked her to put the cigarette out, according to TMZ. Spears also mentioned that authorities greeted her upon landing at Los Angeles International Airport (LAX) - something she initially mistook as a VIP welcome, only to later realise it was due to the smoking incident. Though she was issued a warning, she was not detained. The airline has yet to release a statement. Spears has since apologised for any offence caused, saying she genuinely believed smoking was allowed on that aircraft. HTC...
