NEW YORK, United States (AFP) — United States (US) pop queen Taylor Swift and NFL star Travis Kelce officially married Friday at a lavish wedding that drew a galaxy of fashion-draped A-list celebrities in New York, sealing a union that has triggered frenzied global attention. Excitement has swirled around America's "royal wedding," which is happening on the United States' 250th birthday weekend amid a record-breaking heat wave, a near-total news blackout and a security lockdown of the kind typically reserved for heads of state. The anticipation was even greater as Swift and Kelce made no public announcements about their wedding plans at storied Madison Square Garden -- and reportedly insisted guests sign non-disclosure agreements.
