Lorraine viewers were stunned on Tuesday morning as Dani Behr made an appearance on the ITV show.
Dani, 52, joined Christine Lampard on the programme live from Los Angeles to dish out the latest Hollywood news and looked as glamorous as ever.
The blonde TV presenter resides in California and has clearly adapted the A-Lister lifestyle and look.
As she chatted away about the recent 'Bennifer' wedding as well as some luxurious LA homes that are up for sale, Dani modelled a stylish blonde blowdry and wore a hot pink top with sexy specs.
Viewers clearly didn't realise it was Dani at first and took to Twitter to comment.
"Jesus that’s Dani behr #lorraine," one person posted while another shocked viewer tweeted: "That's Dani Behr. #Lorraine."
A third person admitted: "Wow I didn’t recognise Dani Behr #lorraine."
And a fourth viewer said: "That’s The Big Breakfast’s Dani Behr?! I would never have recognised her other than her voice. #lorraine."
Dani first found fame in 1989 when she made a brief appearance in Grange Hill and was then a presenter on the late night Channel 4 music show, The Word, for five years.
She went on to feature in over 30 TV shows, including The Big Breakfast, Hotel Babylon, Ice Warriors; and in 2001 she co-presented on the first series of the BBC's flagship children's programme The Saturday Show.
After numerous presenting jobs for shows in the US, Dani decided to move permanently to Hollywood to begin presenting Extra for NBC.
She went on to host several more shows for Fox, NBC/Bravo, VH1, including the 2003 reality show Boy Meets Boy.
In between TV, Dani has also presented radio shows for Kiss 100, and has had some minor film acting roles and appeared alongside Kate Winslet, Oprah Winfrey, Glenn Close in the play The Vagina Monologues both in London at The Old Vic and on Broadway at Madison Square Garden.
The mother-of-two also made an appearance on ITV's I'm a Celebrity... Get Me out of Here! back in 2008 and has also been on Come Dine with Me.
Lorraine airs weekdays at 9am on ITV and ITV Hub.
