TEXAS, Oct 23, (Agencies): Prince Harry was all smiles on Sunday as he stood in the temperate Texas sun and enjoyed some high-speed racing. The Duke of Sussex was spotted in Austin at the Formula 1 Lenovo Grand Prix at the Circuit of the Americas, where he was reportedly a guest of the Mercedes-AMG Petronas F1 Team, according to Town & Country.

Harry attended the high-octane racing event without his wife, Meghan Markle, by his side and was spotted chatting with bosses and execs for Team Mercedes in the paddock before the race. The author and father of two sported a black polo shirt and dark jeans, as well as a slick pair of shaded aviators, as he strolled through the racing venue, which housed the three-day F1-focused event.

Harry was also photographed chatting with techs and execs with the Red Bull Racing team, and getting a behind-the-scenes look at their set-up for the big day. While Harry went solo to the F1 event, the Duke and Duchess recently made a public appearance together at the Archewell Parents Summit during the Project Healthy Minds World Mental Health Day Festival in New York City on Oct. 10, where they discussed the impact social media has on kids.
