Prince Harry has reportedly commenced “royal marriage protocols” so he can marry Cressida Bonas as soon as possible. Rumours abound that the 29-year-old British royal has already proposed to the 24-year-old socialite after dating for 18 months.

According to OK! magazine, Prince William’s younger brother still needs to go through royal protocols before he can obtain approval in marrying Cressida, which means he would have to formally ask his grandmother Queen Elizabeth II’s permission.

“Palace sources say there’s not been a formal request made to her majesty yet, but the fact we’re hearing about it means it’s likely he’s already popped the question and they’re waiting until all the boxes are ticked before formally announcing it,” an insider told the U.S. magazine.

Apparently, Cressida is basically already living with Harry at the Kensington Palace, which is deemed an improper royal arrangement.

“Cressida has been staying with Harry pretty much every night for the last few weeks. So Harry felt it was sensible that she got the security clearance to come and go as she pleases, instead of always having to enter with him,” a source told Grazia magazine.

“She’s now on first name terms with all the security guards, and uses all three entrances to the palace.”

Although Harry and Cressida’s living arrangement isn’t an ideal one, it appears that they wouldn’t have to worry about the Queen giving her blessing to their union.

“It’s no secret the queen would dearly love to see her roguish grandson settle down, and she thinks Cressy is his ideal match,” the source continued to OK! magazine.

“She likes that [Cressy] comes from a good family, plus she has a twinkle in her eye that reminds [the queen] of her sister, the late Princess Margaret.”

Harry is eager to leave his bachelor status behind after seeing how happy William is with wife Kate Middleton and son George.

“Seeing how happy his brother is ow and how amazing his nephew is, Harry wants all that for himself.”
