The Reality Killed The Video Star singer reportedly proposed to long-time partner Ayda Field last week, and is said to be eager to make their union official.
A source told the Daily Star: "Robbie doesn't want to have a long, drawn-out engagement. When he gets something in his head, there's no stopping him.
"He's asked all his friends and family to keep the entire week free leading up to February 14, so they can have a week-long celebration before Valentine's Day."
The insider added: "He has asked best friend Jonathan Wilkes to be best man and it's likely Take That will perform."
