Barron Trump debuted a sleek new hairstyle with his hair slicked back as he attended his father’s historic second inauguration on Monday.

The 18-year-old looked sharp in a long black overcoat, paired with a white shirt and purple tie, as he joined a church service at St. John’s Episcopal Church, located just across from the White House, on Monday morning.

Standing at an impressive 6’9″, the NYU-Stern student towered over both his parents, Donald and Melania Trump. Barron kept a neutral expression as he made his way into the church and sat quietly in a pew next to his family.

Interestingly, Barron’s hairstyle bore a striking resemblance to the one often worn by his older half-brother, Donald Trump Jr., 47.

This polished look was a far cry from his appearance during his father’s first inauguration back in January 2017, when a then 10-year-old Barron had blonde, ungelled hair.

At that event, Barron was seen smiling and sharing lighthearted moments with his father at the White House after Donald Trump was officially sworn in as the 45th president.

Barron is the youngest of Trump’s five children. Trump also shares daughter Tiffany, 31, with his second wife, Marla Maples, 61. His three eldest children, Don Jr., Ivanka, 43, and Eric, 41, are from his first marriage.
