A source recently told Us Weekly that Prince Harry and "Suits" star Meghan Markle have decided to marry and are planning on living together soon. Prince Harry reportedly commissioned a ring for Markle with diamonds from his late mom Princess Diana's brooch.

Prince Harry and Markle have yet to announce an engagement or even hint any plans to get married. However, reports claim that the couple may reveal they are engaged around New Year. "It will definitely be a summer wedding," a source said.

Despite the lack of confirmation, many are convinced that Prince Harry and Markle are indeed engaged. In fact, Queen Elizabeth reportedly opened her jewelry vault to have Markle pick a tiara for her big day. Lending Markle a piece from her collection is the monarch's engagement gift to the actress.

Markle is already in the United Kingdom. She reportedly flew from Toronto to London over the weekend. Markle is expected to move into Prince Harry's place in Kensington Palace. "There are no plans for them to live separately," one of Markle's friends said. "Meghan will move right in."

Earlier this year, Prince Harry had his pad renovated. One source claimed that the royal was in a hurry to have it done as he could not wait to have his girlfriend move in with him. "He keeps popping round and asking when it will be ready," one source said. "He seems in a real hurry to move in with Meghan."

People added that Markle was spotted at the palace earlier this year. She was seen carrying Whole Foods shopping bags, picking up flowers and visiting a spa in Soho on the eve of Pippa Middleton's wedding. However, reports claim that the invitation to have tea with the queen last month may be the clearest indication of the seriousness of Prince Harry and Markle's relationship.

"Harry has made no secret of the fact that he wants to marry her," one insider told the publication. "She is the one."

As for Prince Harry and Meghan Markle's specualted, upcoming wedding, they will reportedly have a low-key ceremony. The couple will also keep the wedding private. "Pomp and pageantry is the last thing he would want," a source told Us Weekly. "I can see him wanting to get married at St George's Chapel at Windsor Castle. It would stop it from turning into a total media circus and give the day a sense of privacy that Harry so badly craves."
