Prince Harry and Meghan Markle may announce their engagement this week.

It's the last week of November and the palace is expected to announce the "Suits" star's engagement to Prince Harry soon. According to The Guardian, the engagement announcement speculation reached a fever pitch over the weekend. Last week, TV crews were set up outside Kensington Palace in anticipation of the big reveal of Prince Harry and Markle's decision to tie the knot, but it never came.

However, there is a new sign that their engagement may be announced this week. According to Daily Mail, Prince Harry's girlfriend was being guarded by the Met Police's Protection Command when she was spotted shopping at King's Road in Chelsea on Tuesday.

Aside from being assigned security detail, Markle was reportedly taught by specially trained officers some tips to keep herself safe from terrorist attacks. She was also informed what she should do if she's taken hostage.

This is the first time that Markle has been seen with security personnel in England. Kate Middleton only received police protection after she became secretly engaged to Prince William following their trip to Kenya. It happened almost a month before the Duke and Duchess of Cambridge officially announced their engagement in November 2010.

The publication speculated that Prince Harry and Markle may announce their engagement on Tuesday. Prince William and Prince Charles made their engagement announcements on this particular day of the week, so Prince Harry might do the same.

Richard Fitzwilliams, a royal commentator, said in October that the "Horrible Bosses" star's engagement to Prince Harry might likely happen at the end of November. The couple reportedly opted to delay the announcement so they would not steal the limelight from Queen Elizabeth II and Prince Philip, who celebrated their 70th wedding anniversary last Monday.

"We are confidently expecting an engagement between Harry and Meghan," Fitzwilliams said. "But it isn't likely to be announced before the Queen and the Duke's Platinum Wedding Anniversary in November."

Last week, a source told Us Weekly that Prince Harry and Markle are already engaged. In fact, the "Dater's Handbook" star is reportedly moving into the palace to live with Prince Harry.
