InstagramSpending a birthday behind bars probably wasn't on Chris Brown's wish list.
But ish happens... and the Loyal singer rang in his 25th Monday in the Los Angeles County jail.
Despite being locked up, Brown's on-again, off-again girlfriend Karrueche Tran sent him a special birthday greeting.
Tran posted a sweet pic on Instagram of the two at a previous b-day celebration, along with the caption: "Happy Birthday Christopher...I love and miss you.. Can't wait to give you a big kiss and hug ❤️"
Here's hoping Brown has access to a computer.
On May 1, a judge ordered that Brown remain locked up for alleged probation violation, just hours after he was accompanied by U.S. Marshals on a cross-country trip from Washington, D.C., to Los Angeles on the federal government's inmate transport system, known as "Con Air."
The Grammy-winning singer, who was first jailed on March 14 after being asked to leave the rehab facility he was staying at, was told he must stay locked up for at least another week while his lawyer negotiates with prosecutors about a possible plea deal.
Brown's alleged violation stems from the five years of probation he was sentenced to in 2009 after he pleaded guilty to assaulting then-girlfriend Rihanna.
Brown is still awaiting trial in D.C., where he was arrested and charged with assault, following an alleged altercation with another man on Oct. 27.
Before being taken into custody, the Grammy winner had spent nearly five months in court-ordered rehab.
But being locked up hasn't slowed down Brown's career...too much.
On Mar. 24, he dropped a star-studded video for his latest single "Loyal," which featured guest appearances by Usher, Tyga and Lil Wayne.
