Brand Beckham is moving from the "City of Angels" to the "City of Light."
Soccer star David will take former popstar wife Victoria and their four children back to Europe, with big-spending French club Paris Saint-Germain confirming that the former England captain has passed a medical and signed a short-term deal ahead of Thursday's transfer deadline.
The 37-year-old was later unveiled at a press conference, ending speculation about his next destination following the end of his six-year spell with U.S. MLS team Los Angeles Galaxy in early December.
Beckham said he will donate the wages earned during his five-month contract to a children's charity in Paris.
"It's something exciting and something I'm not sure has been done before," he told reporters, and revealed that his family will be based in his hometown London.
He had been linked with a host of clubs around the world but, in the twilight of his career, has decided to join a team on the rise thanks to the injection of hundreds of millions of dollars by its Qatari owners.
"It's simply a very nice piece of short-term brand alignment that will be mutually beneficial to both parties," sports business expert Simon Chadwick told CNN.
Beckham is one of the world's most recognisable names, both for his sporting prowess and numerous off-pitch endorsement deals, and his pulling power could provide a valuable income stream for PSG -- which must conform to European football's financial fair play rules that restrict over-spending by club owners.
"I think it's very difficult to quantify," Chadwick said. "He's been away from Europe for too long -- he's now really in his twilight years, we don't know what part he'll play in the team, we don't know how he'll be used for commercial purposes, we don't know how the French public will respond.
"And we don't know how international fans will engage with and consume the PSG/Beckham brand. We may see a spike in activity such as increases in ticket sales, but I am not entirely convinced that there'll be a significant sustainable stream of revenues."
However, one leading football executive who had unsuccessfully tried to persuade Beckham to join his team said that the midfielder still had a strong role to play on and off the pitch.
"Not only were we looking for a playmaker in midfield but also a leader in the dressing room and someone to set the standards on and off the pitch. Beckham would have brought all that," the executive told CNN on condition of anonymity.
"Sure Beckham would have ensured exposure and possibly commercial opportunities, but without the quality as a player it wouldn't have been at all interesting."
Beckham had the chance to join PSG in January 2012, but opted to stay in the U.S., ending his American mission with his second MLS Cup title before announcing that he would not fulfill the second year of his contract extension.
"I chose Paris because I can see what the club are trying to do. I can see who the club are trying to bring in," he said Thursday.
"It's an exciting city and now there's a club that's going to have a lot of success over the next 10, 20, 30 years. I'm very honored I've been picked to be part of the future of PSG."
One man who saw him up close in the U.S. believes the former Manchester United and Real Madrid star still has what it takes to perform on the big stage.
"At first it is like the marketing -- you bring in him more for the brand than the player," said former PSG defender Didier Domi, who played in the MLS for New England Revolution in 2011.
"But when I watched him in the MLS he still has the physical condition to play at the highest level. He likes to compete. On the pitch he can add a lot.
"They are not signing him for his ability to sprint -- it's his technique and vision. He has that ability to elevate his game depending on the opposition. He can play a part for PSG in both Ligue 1 and Champions League."
"Les Parisiens" are seeking to win the French title for the first time since 1994, having been runner-up last season.
The club's owners, the Qatar Investment Authority, have splashed out on top players such as Zlatan Ibrahimovic, Thiago Silva, Javier Pastore and Lucas Moura since taking over in 2011.
Carlo Ancelotti's team tops the Ligue 1 table on goal difference after 22 of 38 rounds in the 2012-13 campaign, and will play in the knockout phase of Europe's top club competition in a two-legged tie against Spanish club Valencia on February 12 and March 6.
Former AC Milan coach Ancelotti managed Beckham during the former England captain's first loan spell with the Serie A club in 2009.
However, Beckham might be struggling to be fit for those matches, according to the manager of English club Arsenal -- who allowed the veteran to train with his squad this month.
"He told me that he doesn't look at all to be in shape. Beckham is super-ambitious," Arsene Wenger told reporters this week.
"If, in his mind, he wanted to play in the Premier League he would not have gone on holiday. He would have prepared and come in and tried to impress me. He told me he has done nothing at all."
Beckham admitted it might take "a few weeks" to get fully fit.
"It won't take long," he said.
He explained that he could not play for another club in England except Manchester United, where he won six Premier League titles and the Champions League before moving to Spain in 2003.
"It's the team I support and the team I dreamed of playing for," said Beckham, who to Manchester as a teenager and progressed through the club's academy.
"I'm very honored by the offers I had from other Premier League clubs but I didn't want to play there unless it was for Manchester United."
