SEE PICS Prince William planning Christmas proposal to Kate Middleton?
It's rumoured the prince will wait until Christmas to pop the question as he's tied up with his military training until them.
‘An engagement will happen and there is a possibility of Christmas,’ says Ingrid Seward of Majesty magazine.
‘But a wedding will all depend on the Royal Family’s diaries. It is not very romantic, but it will have to be fitted alongside other possible engagements.’
On Saturday Kate, 26, helped Wills celebrate his 26th birthday at a polo match in the Cotswolds.
The couple were pictured talking intimately at the event before heading to the annual Beaufort Polo Club party.
‘They both seemed really happy, larking around and letting off steam,’ a source tells the Daily Mirror. ‘Kate looked amazing. William could not take his eyes off her.’
