Prince Harry and girlfriend Meghan Markle had their first public kiss at the Audi Polo Challenge event in Ascot on Sunday.
The 32-year-old royal and the 'Suits' actress were spotted smooching and cuddling in the car park at the racecourse in Berkshire, England on Sunday and Meghan is believed to have spoken with the flame-haired hunk's former Army officer mentor Mark Dyer.
An insider shared that Harry and the 35-year-old beauty's relationship is getting serious and that Mark is very pleased with his pal's choice in girlfriend.
According to the Daily Mail, a source said: "Dyer's opinion is important to Harry.
"Mark really likes Meghan. They have been getting on like a house on fire."
Meghan has only been dating Harry - the grandson of Queen Elizabeth and Prince Philip - for just over a year, but she has been welcomed into the family with open arms.
A source recently said: "She's very much been accepted into the family. They are so happy to see Harry happy."
She is even believed to have her own direct line to Harry's royal aide, Edward Lane Fox, for when she needs help with royal protocols.
The source explained: "There have been many times where Meghan's been unsure of protocol, and having access to Harry's aides has been a godsend."
When she visits the royal's London residence, Kensington Palace, she doesn't have to go through any checks like other members of the public.
Insiders said Meghan is waved right through" as "Harry has made it clear she's to be treated like everyone else who lives there".
Meghan's relationship with the prince is going from strength-to-strength as she is reportedly even invited to his sister-in-law Duchess Catherine's sister Pippa Middleton's wedding to fiancé James Matthews.
The Canadian-born star will be with Harry at the party after the wedding at St Mark's church in Engelfield, England on May 20, but not at the service of Pippa, according to PEOPLE magazine.
A source previously told the publication that there is a strict rule that royals who are not married to their partners cannot bring them to this kind of event.
