Guy Berryman, bassist of British rock band Coldplay, has reportedly popped the question to his lady love Keshia Gerrits, after dating her for two years.
The 35-year-old is said to have proposed to Gerrits, 23, last month.
"They're really loved-up and are already planning to get married in a secret London location," a source told the Daily Mirror newspaper.
Berryman's bandmates will attend the wedding along with their partners, but the couple is keen that their romantic ceremony should be a small affair, with just close friends and immediate family in attendance.
The source said: "Of course Chris Martin and his wife Gwyneth Paltrow will be there, as will the rest of the band and a selection of close friends from the group's intimate circle."
The pair first sparked rumours they had got engaged after Gerrits posted a picture on her Twitter account of a diamond sparkler on her ring finger last month.
