The bash was held at the home of Pippa and sister Kate Middleton's parents, Carole Middleton and Michael Middleton, in Bucklebury in England, located about 50 miles west of the prince's Kensington Palace home in London, where the American Suits actress has been staying.
Meghan was not spotted at Pippa and James Matthews' wedding ceremony, held at St. Mark's Church on a private estate six miles away from the house. Harry was seen there without her, walking next to his brother and Kate's husband Prince William.
The reception marks the first event she has attended with the prince's family, fueling speculation among fans that an engagement is imminent. Kensington Palace confirmed their relationship in November.
