The 'Bodies' singer only got engaged last week but is desperate to make Ayda Field – who he has been dating for around three years – his wife, and has earmarked the romantic day as a possible wedding date.
A source told the Daily Star newspaper: "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 35-year-old star is hoping to whisk loved-ones over to Santa Barbara, California, for the ceremony and he has already looked around two prospective venues.
The nuptials are set to be a star-studded event, with his former Take That bandmates Gary Barlow, Howard Donald, Mark Owen and Jason Orange and other celebrity pals set to attend.
The source added: "He has asked best friend Jonathan Wilkes to be best man and it's likely Take That will perform."
