Britain's Queen Elizabeth is set to appear on 'Antiques Roadshow'.
The 88-year-old monarch and her husband Prince Philip met with the BBC One show's team of experts for an appraisal of some of their most treasured royal heirlooms during their three-day visit to Northern Ireland.
The queen proudly showed off her antique collection at her official residence of Hillsborough Castle, near Belfast, where the discussions were filmed as part of a special episode of the long-running series.
Philip was keen to find out when the scenes would air, with the queen chiming in as she signed the visitor's book, "If it is in August then even better because we might have a chance to see it."
Among the items on show was a bronze sculpture of a horse and jockey by French artist Pierre Jules Mene, thought to be of the 1863 Derby winner Macaroni, a George IV library, an 18th century Chinese soup tureen and five figurines from a Meissen monkey orchestra, the BBC reports.
The royal couple spent about 10 minutes with experts before hundreds of people gathered to have their own items valued for the special episode.

Britain's Prince Edward officially opened the Royal Norfolk Show yesterday (25.06.14).
The Earl of Wessex kicked off his duties as the new president of the Royal Norfolk Agricultural Association by opening the show in the grand ring after receiving a military welcome by the Band of the Brigade of Gurkhas, led by Major Paul Norley.
Edward told the crowd: "Although the Royal Norfolk Show is not the is not the oldest, the decision to move to a permanent showground was pretty revolutionary. It is the role of this show to demonstrate the best of what Norfolk produces."
The 50-year-old royal, who is Queen Elizabeth and Prince Philip's youngest son, chatted to youngsters learning about farming and agriculture in the Discovery Zone.
He was described as "very friendly" by members of the Norfolk Young Farmers group, who shared their experiences of taking part in the Duke of Edinburgh award with him.
Christopher Nix, the show's steward, commented to the Norfolk Advertiser: "Lots of people are very pleased to see him."
Edward is the first member of the Royal Family to attend both days of the Royal Norfolk Show in 60 years, following in his grandmother, the Queen Mother's footsteps.

Emma Willis and Christine Bleakley are in line to replace Holly Willoughby on 'This Morning' when she goes on maternity leave.
ITV bosses have reportedly narrowed down their list of potential co-hosts for Phillip Schofield when Holly, 33, takes a leave of absence to welcome her third child with husband Dan Baldwin in the summer.
Silver-haired Phillip, 52, is said to be urging bosses to hire his former 'Dancing on Ice' co-host Christine, as they are good friends and socialise outside of work with their respective partners.
But Emma has also impressed producers with her stints on 'Big Brother' and 'The Voice'.
A source told The Sun newspaper: "Phillip is good friends with Christine and wants her to get the job - but bosses are also looking at Emma."
The coveted job could last for up to a year while pregnant Holly, who already has son Harry, five, and three-year-old daughter Belle, is away.
Both brunette beauties have plenty of experience on 'This Morning' as Emma, 38, presents The Hub section of the show on a regular basis, while Christine, 35, has previously filled in for both Holly and Phillip on the sofa.

Diane Langton would return to 'EastEnders'.
The 67-year-old actress - who is currently starring as Nana McQueen on Channel 4's 'Hollyoaks' - previously played Cindy Beale's mother Bev Williams on the BBC One soap and hasn't ruled out reprising the role in the future as she still has ties to Albert Square because of Bev's grandchildren Peter Beale (Ben Hardy) and Cindy Williams (Mimi Keene).
Diane told Inside Soap magazine: "They keep mentioning Bev on telly at the moment. She's meant to be in Devon, which is really weird.
"You know, I haven't been asked to return to the show, but I guess while the grandchildren are around there's still a possibility."
Diane also admitted she was shocked by the recent storyline which saw the murder of her on-screen granddaughter, Lucy Beale.
She said: "I do like watching 'EastEnders', but I haven't got a clue about who killed Lucy Beale."
Meanwhile, the 'Only Fools and Horses' veteran is enjoying a more prominent role in 'Hollyoaks' following the departure of the McQueen matriarch Myra (Nicole Barber-Lane) last year.
She said: "It's a madhouse for me at the moment! But it's marvellous to be wanted. It's better than coming into scenes and asking people if they want a cup of tea. When Myra left the show, I slipped into her shoes as head of the family. It's been great."

Girl Thing's Linzi Martin has auditioned for 'The X Factor'.
The 32-year-old singer, who recently reunited with the 'Last One Standing' group on ITV2's 'The Big Reunion', came face-to-face with the band's former manager Simon Cowell at auditions last week - but her bid for a pop comeback was short-lived.
Linzi reportedly broke down while telling the judges - including Louis Walsh, Mel B and Cheryl Cole - about her previous attempts at pop stardom.
A source told the Daily Star newspaper: "Her tears didn't really wash with the panel."
Simon, 54, created Girl Thing in a bid to rival the Spice Girls' popularity, but the band - also consisting of Jodi Albert, Anika Bostelaar, Michelle Barber and Nikki Stuart - failed to connect with the public and were unceremoniously dropped after just two single releases.
Earlier this year, the music mogul blasted his former act by branding them "bitter".
On 'The Big Reunion', Linzi claimed she wrote some of the verses for the hit Hear'Say song 'Pure and Simple', which was originally recorded by Girl Thing.
Simon offered his two cents on the drama, telling BANG Showbiz: "What happened was, the guy that was managing them, I got him the gig to manage 'Popstars' [winners], Hear'Say. He gave my song, 'Pure and Simple', to Hear'Say. It was my hit record.
"That's why we didn't do what we hoped we were going to do with that group. It's as simple as that."

David Hasselhoff is to star in a new British TV comedy.
The former 'Baywatch' star has revealed he is moving to the UK to film a six-part, semi-improvised series named 'Hoff The Record' - from the makers of Karl Pilkington's 'An Idiot Abroad' - which will air on Dave next year.
Speaking about his new project, David said: "'Hoff The Record' is coming to the UK, only on Dave. They did name the channel after me, right?"
The new programme will be shot in the style of a documentary and is about the life of 'The Hoff', a fictionalised version of the star.
A member of the 'Hoff The Record' production team told The Sun newspaper: "We are thrilled to work with David and are amazed he's game to play a jaw-dropping version of himself for us."
The 61-year-old actor first let slip that he was planning to work with the channel Dave on Twitter last month in a message that was later deleted.
David's last British TV stint was as a judge on 'Britain's Got Talent' in 2011 alongside Amanda Holden and Michael McIntyre.
The 'Knight Rider' star is currently dating Welsh beauty Hayley Roberts, whom he met while in the UK for 'BGT'.

Demi Lovato has a crush on Amber Heard.
The 'Skyscraper' hitmaker is in awe of the bisexual 'Rum Diary' actress - who is engaged to Johnny Depp - and thinks she is one of the most beautiful people she has ever seen.
Asked who her girl crush is, she said: "I love Amber Heard. She's so gorgeous, it's ridiculous."
Demi is a vocal campaigner for gay rights and revealed at Logo TV's Trailblazers event earlier this week that her late grandfather was homosexual and came out in the 1960s.
Though he died long before she was born, the 21-year-old star is convinced she has inherited her opinionated ways from him.
She told E! News: "It makes so much sense as to why I feel so connected to standing up for what I believe in.
"When I heard the word 'trailblazer,' I automatically thought of my grandfather and him coming out in the '60s. It's very powerful. I couldn't be more proud of him."
Demi recently filmed the video for her new single 'Really Don't Care' at Los Angeles' Pride event and says the track's meaning has changed for her since it was first written.
She said: "When I originally wrote it, it was a break-up song.
"But now I have sung it so many times that it kind of no longer has a significance in that sort of way. When I sing it, I always want to inspire and empower. I thought what other people could relate to really not caring what people think. I thought of bullies and the LGBT community who are constantly scrutinised. What better place is there than L.A. Pride to celebrate who you are and not really caring what people think?"

Ed Sheeran couldn't date a woman with no sense of humour.
The 'Sing' hitmaker - who confirmed earlier this year he is dating someone out of the public eye - thinks laughter is the key to a successful relationship and couldn't be with someone who took themselves too seriously.
Asked his favourite quality in a woman, he said: "A sense of humour. I think that's key for any long-lasting relationship.
"[Have I ever dated anyone with no sense of humour?] I have more sense than that, but I speak to women with no sense of humour quite a lot.
"I met this model last year. Her meal for the day was a cotton ball soaked in Diet Coke. I don't want to be friends with somebody like that."
The 23-year-old star also admitted he enjoyed selling out New York's huge Madison Square Garden venue a lot more than losing his virginity.
Asked which feat was better, he told the new issue of America's ELLE magazine: "Probably selling out Madison Square Garden three times.
"Losing my virginity was a benchmark in my life, but it wasn't the best thing I've ever done."
The 'A Team' hitmaker insisted he wouldn't be upset if his girlfriends didn't like his music, so long as they had respect for his work.
He said: "[Could I love someone who didn't love my music?] Yeah, yeah.
"I think there's a difference between loving the work and respecting it. If I dated, I don't know, a horse jockey--I'm not a massive fan of horse races, but I could still respect what the person does."

Little Mix's Jade Thirlwall and Jesy Nelson have split from their boyfriends.
The pair - who make up half of the 'X Factor' winning girl group - were both dating members of 'Britain's Got Talent' dance troupe Diversity but are said to have ended their relationships because of their hectic schedules.
A source close to the 'Salute' hitmakers told the Daily Mirror newspaper: "It happened very recently for both couples."
Jade, 21, had been dating Sam Craske since 2011 while Jesy, 23, had been dating Diversity leader Ashley Banjo's younger brother Jordan at around the same time, although they previously split in March last year before getting back together.
The source added: "While it's strange timing and quite a coincidence that both girls were dating boys in the same dance troupe, it seems to have stemmed from the amount of time they are able to spend together, because of their conflicting schedules.
"The girls are about to go on a huge US tour, which will see them spend the entire rest of the summer apart.
"That's tough for any relationship, but especially when the girls are still so young."
Meanwhile, Jesy and Jade's bandmates Perrie Edwards, 20, and Leigh-Anne Pinnock, 22, are still going strong with their partners, as Perrie is engaged to One Direction heartthrob Zayn Malik and Leigh-Anne is still dating soccer player Jordan Kiffin.

Cara Delevingne is eager for a role in the new 'Star Wars' film.
The model and budding actress is said to be a fan of the popular sci-fi saga and has pressed her actor pal Domhnall Gleeson - who is to star in the new installments of the franchise - to put in a good word for her.
A source told the Daily Star newspaper: "Cara is a huge fan of 'Star Wars'. She became very envious when she heard the unknown actress Daisy Ridley had managed to land a role.
"But there are still plenty of parts yet to be cast, as Domhnall has assured her, and she's desperate for one - no matter how small."
The 21-year-old beauty has been boosting her acting career over the last year with roles in TV drama 'Timeless' and British film 'Kids in Love', which also stars BAFTA winner Will Poulter.
The celebrated fashion darling recently admitted she is scaling back on her modelling career - which includes lucrative deals with Mulberry and DKNY - to concentrate on her film career.
She said: "Acting is all I've ever wanted to do, so I'm living the dream. I prefer acting to modelling. Modelling is where I started and I could never turn my back on it because without it I wouldn't be here, but this is what I love. This is it for me."

Lana Del Rey is dating an Italian photographer.
The 'Young and Beautiful' hitmaker - who recently announced she had split from boyfriend Barrie-James O'Neill - has been spotted with Vogue photographer Francesco Carrozzini on dates in both Los Angeles and New York this month, and insiders claim the new romance is already getting serious.
A source told the New York Daily News newspaper: "She came off her tour to see him in New York. Even his ex, Katherine Keating, knows they're a couple."
News of the new romance may comes as a surprise to rocker Barrie-James, as he has insisted he and Lana are still together.
He said: "It's not over. It's not over. Don't believe what you read, it's not over. It's just stories, bedtime stories."
The Nightmare Boy star also revealed that he and Lana, 28, are also still working on new music together and praised her new album, 'Ultraviolence.'
He said: "We have done for a long time... 'Ultraviolence' is ultra good."
Lana claimed in an interview last week that she and Barrie-James, whom she first began dating in 2011, had split because she wanted to feel "free," but hinted they might get back together again.
She said: "We are currently not together. He is a wonderful person. But there are some things with which he has to deal. I will not explain it in detail. This was hard on our relationship, I no longer felt free. We'll see how it goes."

Beyonce has paid tribute to the late Michael Jackson for helping her "become the artist" she is today.
The 'Run the World (Girls)' hitmaker penned a touching letter on her website yesterday (25.06.14) - the five-year anniversary of the King of Pop's death from acute Propofol intoxication - explaining how she learned "soul" from the 'Thriller" star when she was beginning her career.
Under the title 'Inspiration Michael Jackson' and accompanied by an early-1970s picture of the late star, she wrote: "When I was just starting out, my first producer used to make me listen to Michael Jackson's live performance of 'Who's Loving You'. He would have me watch that for hours back to back to back.
"What he wanted me to learn was his soul. You could hear his soul. And he was this little kid who hadn't experienced love but he was a vessel.
"For whatever reason he could evoke more emotion than an adult. It was so raw and so pure. It was these little things that he did that were just swag. It's something that's God given."
The 32-year-old star - who has two-year-old daughter Blue Ivy with husband Jay Z - went on to explain she had learned to be free with her singing and not always worry about technique thanks to Michael.
She added: "Michael taught me that sometimes you have to forget technique, forget what you have on. If you feel silly, you have to go from the gut just let it go.
"Michael Jackson changed me, and helped me to become the artist I am thank you Michael."
The message was then signed off "Love always, B."
Last night, Beyonce and Jay kicked off their 'On the Run' joint tour in Florida.
