was quick to apologise after suffering a blunder minutes into the show.

During Monday's episode, the Welsh star was informing viewers what they could expect to see coming up on the show with her co-star Roman Kemp.

As they saw a clip of King Charles attending the Chelsea Flower Show, Roman highlighted that Alex attended with her dog.

She said: "Yes, we visited Monty Don's dog friendly garden and we'll find out how well behaved Scout was in just a moment and I'll be showing you around some of the other stunning gardens as well on display, it was a lovely day."

Roman asked if Scout was well-behaved as she pulled a face, insinuating he wasn't. Wrapping up the introduction, Alex tried to continue informing viewers what was coming up before she began to cough.

She said: "Also coming up on the week that gardens are in the spotlight at Chelsea, tonight we're teaming up with the Royal Horticultural Society to, sorry. Oh my gosh, something is stuck in my throat!"

Roman said: "Bit of pollen from earlier, you all good? Have some water."

Although Alex confessed she was fine as she sipped a drink before the pair rolled a pre-recorded clip of Alex and her dog at the Chelsea Flower Show.

Elsewhere in the show, the pair spoke to EastEnders star Anita Dobson about reprising her role as Angie Watts for the soap's 40th anniversary celebrations.

Roman asked: "What was that like getting back there?"

She replied: "It was weird, very emotional and absolutely lovely. It was like stepping a bath of warm water, warm bubbled water. Everybody was gorgeous to me.

"It was wonderful working with 'Tisha (Letitia Dean) again, who plays Sharon. I couldn't believe I got back into the costume! The original costume, I'm very proud of that."

During their chat, Roman asked if there was anything she would change about her life.

Anita replied: "I think you have to own your life, the bad stuff and the good stuff. If you change something then your whole life has to change, it's a completely different journey.

"So, no I'm going to own up and say something's I've done and I wish I done them better but I'm proud of the things I have done and it's got me to be who I am today."
