Buzz Aldrin has announced that he has married his "long-time love" on his 93rd birthday.
The former astronaut has tied the knot with Dr Anca Faur, who is thought to be 63, in a small ceremony in Los Angeles.
He took to Twitter to share the happy news.
He wrote: "On my 93rd birthday and the day I will also be honoured by Living Legends of Aviation, I am pleased to announce that my long-time love Dr Anca Faur and I have tied the knot.
"We were joined in holy matrimony in a small private ceremony in Los Angeles and are as excited as eloping teenagers."
Buzz, who is the second person to step foot on the moon, shared some photos from the wedding showing Dr Faur in a sparkly gown and himself dressed in a smart suit while wearing his medal and his Air Force badge.
The happy news comes after it was announced that Buzz's jacket that he wore on his historic first mission to the moon has become the most valuable American space artefact ever sold at auction, after fetching over £2 million.
The jacket was sold by Sotheby’s in New York on Tuesday as part of the most valuable single space exploration sale ever staged, which achieved a total of 8.2 million dollars (£6.8 million).
Selling for a total of 2,772,500 dollars (£2,303,254) it makes the item the most valuable jacket ever sold at auction.
The jacket displays Aldrin’s name tag on the left above the Apollo 11 mission emblem, and the American flag on the left shoulder.
The jacket was purchased by an anonymous bidder, who participated in the auction by phone.
"Today’s result is a testament to the legendary career of Buzz Aldrin and his lifelong dedication to the exploration and understanding of the universe," said Cassandra Hatton, Sotheby’s Global Head of Science & Popular Culture.
"It has been a privilege to work alongside Buzz to bring such prestigious objects to market for the first time, and today’s record breaking outcome proves the ongoing and everlasting significance of the Apollo 11 Mission, some 53 years since man first walked on the Moon."
