Meghan Markle recently went on an outing in London.

Rumors have been claiming that the "Suits" actress is moving to the U.K. for good after she wraps up her USA Network legal drama. Multiple sources claimed that Markle is done filming for Season 7 and won't be returning for a potential Season 8 as she will be moving across the pond to be with her boyfriend, Prince Harry. And it looks like there may be some truth to the speculation as Markle hasn't returned to Toronto yet after flying to England over the weekend.

On Tuesday, the actress was spotted shopping in London without Prince Harry. She sported a black sweater and jeans. She paired this with gray jacket and scarf that she wrapped around her neck. Markle also wore dark shades for the outing, Entertainment Tonight reported.

"She is planning to make a full-time [move] over to the U.K.," royal expert Katie Nicholl told ET. "I would say this is probably the most significant thing to happen yet in their relationship."

According to reports, she took a flight from Toronto to London over the weekend after filming the "Suits" Season 7 finale. However, it is unclear if the "Dater's Handbook" star attended Queen Elizabeth II and Prince Philip's wedding anniversary celebration on Monday.

Unlike Markle, however, her beau Prince Harry, along with Prince William and Kate Middleton, was present at the monarch's 70th wedding anniversary. The Duchess of Cambridge donned a black lace dress for the special gathering. Meanwhile, Prince William and Prince Harry sported classic black tuxedos. The royal trio arrived together in the same car, apparently without Markle.

In related news, Markle and Prince Harry are expected to fly to Los Angeles to celebrate Thanksgiving with her mom, Doria Radlan. After the holiday, the actress and Prince Harry will be returning to London, and by then, Markle will be moving in with her boyfriend in the palace. "It'll then be time for Meghan to move to London and into Harry's place," an insider said.

Some sources previously claimed that Prince Harry and Markle are already engaged because they have apparently been openly talking about marriage. The public is just waiting for their announcement.

"While Meghan may not be wearing a ring or a formal engagement announced, it's fair to say they're as good as engaged now," the insider added. "They've spoken about their marriage plans openly with each other and friends and family around them are pretty much thinking about wedding attire already!"
