Retired Pope Benedict XVI today toasted his brother Georg on his 90th birthday as they celebrated Mass together and attended a concert in the Vatican gardens.
Monsignor Georg Ratzinger was ordained a priest on the same day as the future pope in 1951 and they share a love of music.
Mgr Ratzinger was a frequent visitor when Benedict, 86, was pope and has continued visiting in Benedict's retirement.
The brothers spent Christmas together at Benedict's retirement home in a converted monastery in the Vatican gardens, and Mgr Ratzinger stayed on a few weeks so they could celebrate his birthday together.
The Vatican said they started their day concelebrating Mass, having a festive breakfast complete with Bavarian songs and toasts and ending with a concert in Mgr Ratzinger's honour.
