Simon Cowell has relaxed since falling in love with fiancee Mezhgan Hussainy
Amanda Holden, who works with the music mogul on UK TV show 'Britain's Got Talent', claims her friend is "different" since he started romancing the make-up artist.
She said: "He has always been relaxed and he is always very tactile with me, or whatever girls sit next to him, but he's different.
"He'd lean back in his chair at the 'Britain's Got Talent' auditions and look at Mezhgan. It's very sweet."
Amanda has given her seal of approval to Mezhgan, saying they hit it off straight away and have quickly developed a strong bond.
Amanda added: "She is lovely. She is a real girl's girl. She'll come and hug me and say, 'Oh you look fantastic, where did you get those shoes from?'
"She just wants to be your friend, which I think is lovely because some girls can be horrid to other girls. She's not like that - she's smashing."
