Coco Gauff lost her second French Open final of the weekend as the teenager and Jessica Pegula were beaten by Caroline Garcia and Kristina Mladenovic in the women's doubles.
Gauff was defeated in straight sets on Saturday by world number one Iga Swiatek in her maiden grand slam final at Roland Garros.
The 18-year-old and her fellow American Pegula started well on Sunday, taking the first set before their French opponents stormed back to win 2-6 6-3 6-2 on Court Philippe-Chatrier.
An early break from Gauff and Pegula gave the number eight seeds the advantage, before another in the seventh game allowed them to serve out the opening set.
However, the experienced Garcia and Mladenovic found several more gears to race out into a 4-0 lead in the second set.
Gauff and Pegula - who was also beaten by Swiatek in the quarter-finals of the singles' event in Paris - came back to 3-4, but were broken again and the French duo grasped the chance to level the match.
The decider was one-sided, with Garcia and Mladenovic again taking a 4-0 lead, before eventually serving out to win as the 2016 champions were able to repeat the trick six years later in front of a delighted home crowd.
Mladenovic has now celebrated four doubles triumphs in her home grand slam - two with Garcia and as many with Timea Babos. This was Garcia's second success.
