"I'll be wearing a wedding dress in case Prince Harry gets cold feet – I want to be ready," Victoria, 24, tells Woman's Day exclusively. "I think I'll take a big picture of us kissing just to remind everyone I had him first. Maybe he'll see it and have a chuckle!"

Having already offered the 33-year-old her hand in marriage three times, the self-confessed royal tragic says she plans to fly to London this weekend and wait outside Windsor Castle in her ivory gown – just in case he gets pre-wedding jitters

As Meghan Markle slips into her designer wedding dress on Saturday, Victoria McCrae – who hit world headlines when she stole a kiss from Prince Harry in 2015 when he visited Sydney – will be donning her own bridal gown.

The Sydney receptionist says her royal obsession began when she visited London with her family when she was 13, on the 10th anniversary of Diana's death. Since then she's been mad about Harry – literally.

The wannabe princess was stopped by police when she kayaked out to meet him on Sydney Harbour in 2013, and in 2014 told Prince William she wanted to marry his brother.

She then went on to catch Harry's attention in 2015 when she stole a kiss from him on the steps of the Opera House while clutching a "Marry Me, Last Chance! Prince Harry" placard.

"I said to him, 'Prince Harry, this is the third time I've asked you! Put a girl out of her misery,'" Victoria recalls.

"Then I asked for a kiss and he turned his cheek, so I just grabbed it and turned his face to me and kissed him. I think he was as shocked as me."
