The 22-year-old not only kept his word but seemed to flaunt his celebrity by posting the photos with the pop star heartthrob as well as boxing champion Floyd Mayweather and others.
Manziel is free from football for the next few weeks. The Browns open training camp July 26, when Manziel will resume his competition with Brian Hoyer for the starting job. Manziel spent last week attending the NFL's rookie symposium with Cleveland's other first-year players.
On Friday, Manziel addressed the clamor caused by his social life he has been filmed spraying champagne on partygoers in Las Vegas, photographed floating on an inflatable swan raft drinking champagne and seen in a video talking on a fake money phone.
Manziel defended his right to party.
"I'm not going to change who I am for anybody," he said. "I'm growing up and continuing to learn from my mistakes and trying not to make the same ones over and over again, but am I going to live in a shell or am I just going to hide from everybody and not do anything? I don't think that's the way I should live my life and I'm not going to do it.
"I'm here. I'm very committed to football. I'm committed to my job, but on the weekends, I'm going to enjoy my time off."
Browns coach Mike Pettine has said he won't speak to Manziel or any of his other players about their off-the-field affairs unless they get involved in criminal activities or it affects their jobs.
Around the league
49ers • Linebacker Aldon Smith will not face charges related to his arrest earlier this year at Los Angeles International Airport. The city attorney's office said in a statement Tuesday that it declined to charge the 24-year-old but will require him to come to a meeting to discuss what happened and be admonished about applicable laws. Smith was taken into custody April 13 after authorities said he became belligerent during a random security screening and threatened that he had a bomb.
Cowboys • Dallas acquired the rights to former Baltimore linebacker Rolando McClain and is placing Sean Lee on season-ending injured reserve with a torn knee ligament. The team reported on its website Tuesday that it also would send a sixth-round pick in next year's draft to the Ravens while getting a seventh-round pick in return.
