Andy Murray and Serena Williams will take on Germany's Andreas Mies and Chilean Alexa Guarachi in the first round of the mixed doubles.
The superstar pairing was first mooted on Saturday before being confirmed on Tuesday evening ahead of the deadline for entries at 11am on Wednesday.
They are in the top section of the draw and would face 14th seeds Fabrice Martin and Raquel Atawo should they come through their opener, which could take place as early as Friday.

Speaking to STV, Murray said: "It'll be great. I'm just happy to be fit and healthy again.
"With what's happened the last year or so, you never know what's round the corner, so it's a great opportunity. I'll look forward to it."
Murray's mother Judy feels the fledgling partnership could be the "perfect match".
"It looks like a really strong partnership," she said.
"It's always difficult to tell in mixed doubles because you only have them in the grand slams, so nobody gets the chance to specialise in it or play it a lot.
"But they've both got form in singles and doubles, so hopefully they can be the perfect match."
Andy is also competing in the men's doubles with Pierre-Hugues Herbert as he continues his comeback after hip surgery.
The draw has thrown up a potential meeting with brother Jamie, a prospect Judy admits would be "torture" for her to watch.
"I've been fortunate that Andy's career has been in singles and Jamie's in doubles, so for family harmony it's been great," she added.
"But if it happens I'll go to the pub, and wait for a text."
The brothers cannot meet until the final in mixed, with Jamie and his American partner Bethanie Mattek-Sands placed in the bottom half of the draw.
Williams' sister Venus is also playing mixed, with fellow American Frances Tiafoe, while 20-year-old British player Jay Clarke is partnering teenage sensation Cori Gauff.
