Oxford-born Jamie Laing is covering Radio 1's coveted Breakfast Show slot this week.
The former Made In Chelsea star, 35,and co-host Matt Edmondson are stepping in for the hugely popular Greg James who is on holiday.
It follows Mr Laing's successful stint on Radio 1 in October 2022 when he replaced Mollie King while she was on maternity leave.
During the show he was overjoyed to be told he had finally passed his driving theory test.
It was revealed that Mr Laing had sat 10 tests, but had booked 70 overall.
On one instance, Mr Laing said he was turned away for being late.

Having passed, he teased that it was only the start of his motoring journey.
He joked: "I'm gonna pass my lorry test next. [...] I'm gonna buy a lawnmower. I'm gonna do it all".
Mr Laing was born in Oxford and attended Summer Fields School in Summertown and Radley College.
He studied Theatre and Performance at Leeds University.
He is great-great-grandson of Sir Alexander Grant, 1st Baronet, who created the McVitie's digestive biscuit in 1892 and went on to build an empire of biscuits brands including McVitie's, Jacob's, Twiglets, Mini Cheddars and Carr's.
However, contrary to rumours, Mr Laing has said that he is not the heir to the huge McVitie's empire.
He has said: "I'm not heir to anything. People always talk about this - I don't know where this has come from.
"We sold the company a long time ago, but I don't know where that money went. I haven't seen any of it. It's pretty upsetting. I'm hoping one day I find it. I don't even get free biscuits."
He presents the Radio 1 podcast 6 Degrees from Jamie and Spencer with his Made in Chelsea friend Spencer Matthews for BBC Sounds.
As well as this, he can also be heard on popular podcasts Private Parts and NearlyWeds with his fellow Made In Chelsea star Sophie Habboo who he married in London in April, before having a second wedding in Spain.
