David Beckham and Lionel Messi appeared in high spirits at an Inter Miami CF training session at Florida Blue Training Center on Tuesday. The former England footballer, 49, who is the clubs co-owner, flashed his dazzling white smile while chatting to Messi, 37. He cut a casual figure in a navy T-shirt, jeans and fresh white trainers while enjoying his morning coffee. Meanwhile, Messi was dressed in his eye-catching pink strip and yellow boots as he strolled onto the pitch. Miami are unbeaten after their first six games of the new MLS campaign. It comes after David and Lionel partied with Tom Brady and other A-list sporting legends as the stars descended on his swanky early 50th birthday party in Miami. The former England soccer player, who doesn't actually turn 50 until May 2, posted several pictures from the bash at the Cipriani Downtown Miami in Florida on Sunday. Among them was a picture with Brady, the seven-time Super Bowl champion and NFL legend, and basketball great Shaquille O'Neal. Brady, 47, and Shaq, 53, who stand at 6ft4 and 7ft1 respectively, both towered over 5ft11 Beckham as they stood together for the picture. Beckham took the sizeable height difference in good spirits though, posting 'I'm so small' alongside the picture on his Instagram story. All three former athletes looked dressed for the occasion in dark suits with Brady opting for a T-shirt underneath is jacket. Beckham also made sure to invite a number of players from his Inter Miami MLS soccer franchise. As well as Messi, the team's star player, Beckham invited Luis Suarez, Jordi Alba and Sergio Busquets. The four players are known to be close friends away from the soccer field and their families are particularly close. All four played together at Barcelona at the club's peak before leaving at different stages and reuniting in Florida under Beckham's ownership. Beckham stood for a picture with all four players before wife Victoria joined him in posing for a separate one with Messi, Suarez and their wives. David was laughing out loud as they posed with Messi, his wife Antonela Roccuzzo, Suarez and his wife Sofia Balbi. Hollywood stars Justin Theroux and Fisher Stevens were also in attendance, as well as Grammy winner Marc Anthony.
