Paul Latham, 32, is behind the funny character 'Grandad' who is a big hit on Snapchat and it turns out Grandad is a big hit with model Tara, too.
In the clip, Tara can be seen lying down on a bed while wearing a low cut top and a black latex skirt - and Grandad approves.
Speaking into the phone he says: "I just had to have a really odd conversation with Kathleen because she is the bill payer, so I just had to ask her for permission to give you a ring, I don't think she was too happy about it, you know what I'm saying?
"We are getting out now, we ain't got long left, she has got to let me have me fun otherwise I am just going to end up running down and old.
"I think she talks to Barry three doors up anyway most Tuesdays, so each to their own, I get my fun and she gets hers, you know what I'm saying?
"But Christ you are in good shape yourself, them chest aren't looking to bad."
Tara appears to be enjoying the conversation and is asking him questions and laughing along.
Grandad, who's 'not freytened of telling you how it is,' has got an impressive 55,000 followers on Snapchat and regularly shares videos of him reminiscing about the 'old times' and making prank calls.
Paul, from Blackburn, has been creating the videos for the last two years and says he does it because he 'likes to have a laugh'. Well, that's as good a reason as any.
He said: "I love making people laugh. This video just hit off straight away, everyone just loves the Grandad character.
"It is just a laugh. I have too much time on my hands, I really need to grow up - I just like to have a laugh that is all.
"I have been doing this for two years and I have aspired to be involved in comedy since my early 20s.
"I have always been able to do accents and impressions.
"I can just do accents off the cuff, I can do London accents, Scouse accents."
