The music mogul - who famously fell out with the Girls Aloud singer after firing her from the US version of 'The X Factor' after just four days in the job - purchased a piece of land in the Scottish Highlands that came with the title.
A source told The Sun: “Simon had the deeds for the land and the details of her new title delivered to where Cheryl was staying.”
She later posted a picture of the land deed on Twitter writing to Simon: "I will now be referred to as Lady Cheryl Cole when you address me both in person & through the media."

Cheryl celebrated her 30th with a lavish £50k party in Las Vegas, and Simon shot down reports he had 'snubbed' the party on Twitter, insisting he only missed the bash because of a clash with his filming dates for 'X Factor USA' auditions.
He wrote: "And I didn't snub Cheryl's party. I just couldn't go because of my filming dates. We are close friends again and I adore her."
Cheryl soon confirmed the pair's renewed friendship when she tweeted back: "don't worry I know. And thank you for my lovely gift!! Xx."
Her Girls Aloud bandmates Nicola Roberts and Kimberley Walsh were among the guests at her party, and a picture of them passed out with Cheryl's boyfriend Tre Holloway appeared on Twitter after they partied until 3.45am.
Other snaps taken from inside the bash show Cheryl puffing on a cigarette inside the venue. Tut tut.
She could also be seen throwing some serious shapes at Hakkasan as she hit the dancefloor in her stunning white dress.
