Welsh opera star Katherine Jenkins is planning to launch her own summer festival in south Wales in 2007.
Katherine Jenkins is the biggest selling female classical artist
The final line-up and a venue for the event are still to be finalised, but organisers say it will celebrate the arts "in all senses of the word".
They also say the "KathFest" will not copy Bryn Terfel's Faenol Festival held in north Wales each August.
Full details of who is taking part in Jenkins' two day festival are to be confirmed over the coming months.
Her own festival is another step in the career of Neath-born Jenkins, who at 25 is the biggest selling female classical artist after notching up record sales of 1.5 million in barely two years.
The former music teacher has now taken on Dame Vera Lynn's mantle as "forces sweetheart" and last Christmas went to entertain troops in Iraq.
She is the mascot to the Wales rugby team and sings the national anthem at most of the team's internationals.
Both Welsh stars will now be staging summer festivals
Jenkins will headline in a concert in London's Royal Albert Hall next month.
She will also perform in Japan and Iceland in April, and with Spanish star Jose Carreras in late May and June.
Now her team is looking at several sites along the M4 corridor in south Wales for her first summer festival and its organisers are promising "a star-studded cast of international singers and performers".
Jenkins' manager Brian Lane said: "We're keen not to just replicate a Faenol type festival in the south of Wales.
"They do what they do very well. We want to present a festival that extends the festival-goers' experience in all aspects of the arts and we have some fantastic ideas in development.
"We've already been planning this for over a year now and although we can't say too much at this stage, we'll have more to tell everyone in the coming weeks and months as this all starts to come to fruition."
Bryn Terfel's Faenol festival, held on the Faenol estate near Bangor and now in its seventh year, has grown to be one of the biggest summer attractions in north Wales.
In 2005, when Katherine Jenkins herself was one of the guest performers, more than 30,000 tickets were sold for the four day event over August Bank Holiday at the foot over Snowdon.
This year the international bass baritone had already confirmed Irish boy band Westlife and Dame Shirley Bassey, are to perform at this year's Faenol concert.
Meanwhile, both Jenkins and Terfel, who is from Pant Glas in Gwynedd, are to appear at the 60th Llangollen International Eisteddfod in July.
Bass baritone Terfel will open the festival with his first appearance on the Llangollen stage since 1995.
