Prince Charles and Camilla Parker-Bowles have weathered numerous issues and controversies since they rekindled their romance in 1986. The Royal couple tied the knot in a civil ceremony on Apr. 9, 2005, at Windsor Guildhall. Recently, Prince Charles and Camilla proved that they are still head over heels with each other even after 14 years since their wedding.

Reports claimed that Camilla traveled to India just to join Prince Charles on his 71st birthday celebration. Hello! Magazine reported the Duchess of Cornwall surprised her husband after his Royal engagements in New Delhi and Mumbai. The publication claimed Camilla treated Prince Charles to a holistic health retreat when they met in Bangalore on Thursday.

Prince Charles and Camilla Parker-Bowles, possibly, enjoyed naturopathic and homeopathic treatments in a retreat center located at a 30-acre organic farm. “The Duchess has been determined to force the Prince to have some downtime on his birthday and insisted he join her at her retreat,” a source told the magazine.

IBTimes, previously, reported that Prince Charles would celebrate his birthday alone in India after it was revealed that Camilla canceled upcoming engagements after falling ill with a chest infection. “The Duchess of Cornwall has been told by her doctor to cancel her engagements owing to a chest infection which has got progressively worse over the last few days,” a spokeswoman for the couple said in a statement.

Aside from the Camilla, Prince William, Kate Middleton, Prince Harry and Meghan Markle also greeted Prince Charles on his birthday. The Duke and Duchess of Cambridge shared three photos of the Prince of Wales alongside Prince Louis, William and Harry. "Wishing a very happy birthday to The Prince of Wales!" they wrote in the caption.

Prince Harry and Meghan Markle also wished Prince Charles a happy birthday by sharing a black and white photo of him during baby Archie’s christening on Instagram. "Happy birthday to His Royal Highness The Prince of Wales – Sir, Pa, Grandpa!" the caption read.

Meanwhile, Prince Charles and Camilla Parker-Bowles are set to start their New Zealand tour on Sunday, Nov. 17. The couple is, reportedly, visiting Kaikōura, the Waitangi Treaty Grounds and Christchurch. Prince Charles and Camilla will be the first members of the Royal clan to visit the historically significant spot in Waitangi in 25 years.
