ITV Our House fans convinced royal lookalike is related to Kate Middleton

ITV viewers have spotted a royal lookalike in new drama, Our House. Downton Abbey star Tuppence Middleton and Line of Duty’s Martin Compston lead the cast of the four-part thriller.

Episode three picked up with Fi Lawson (played by Middleton) still struggling to come to terms with losing her home. Turning to new partner Toby for support, Fi continued to search for her estranged husband Bram (Compston).

But many viewers found them distracted by Fi’s appearance, with several claiming that actress Tuppence Middleton was the spitting image of Kate Middleton, the Duchess of Cambridge. Fans took to Twitter to comment on the similarities between the two.

Polly @joy9kat tweeted: “Fi does look very much like Kate Middleton.”

Aaron @AStevens591 agreed, writing: “I’ve decided Tuppence Middleton is related to Kate. She says she’s not but really she is. Look at her!”

Elsewhere, Donna @DonnaWood17 mused: “Keep thinking how much like Kate Middleton the lead actress in #OurHouse is, then realised her name is Middleton! Any relation?”

Our House viewer Traylor @TraylorHolmes asked: “Are we sure Tuppence Middleton isn’t related to Kate?”

Twitter user @georgelepaws1 joked: “The Crown will be after Fi to play Kate.”

And Dean @PortsLeedsNI said: “Tuppence Middleton looks like she could actually be Kate’s sister.”

Despite physical similarities – and a shared surname – Kate and Tuppence Middleton are unfortunately not related. Our House star Tuppence previously spoke out about the comparisons, saying: “Since Kate Middleton came around, some people think I’m related to her, but unfortunately, there’s no connection.”

Our House continues on Thursday, March 10 at 9pm on ITV and ITV Hub. All episodes are available to watch on ITV Hub now.
