The 'Crazy, Stupid, Love' singer tied the knot with Jean-Bernard Fernandez-Versini in a secret ceremony last week after just a few months of dating, and her former Girls Aloud bandmate insists the depth of her feelings for the French businessman mean she hasn't rushed into things.
She tweeted: ''For the Versinis', but mostly for her, who is happier than ever. Love. xo.(sic)''.
The message was accompanied by a picture of a quotation which read: ''You can be in a relationship for two years and feel nothing; you can be in a relationship for two months and feel everything.
''Time is not a measure of quality; of infatuation, or of love.''
Meanwhile, Cheryl's new engagement and wedding rings have been estimated to be worth a staggering £300,000 by celebrity jewellery Vashi Dominguez.
The jeweller explained: ''Cheryl has been presented with an emerald cut diamond engagement ring by Jean-Bernard.
''Reminiscent of Kim Kardashian's emerald cut choice following her recent wedding to rapper Kanye West, the ring is
crafted from platinum in a wide band and mounted with two large side stones for that added sparkle.
''Cheryl wears the showstopper with an elegant channel set diamond wedding ring - a popular choice which is understated and sophisticated yet still beautifully eye-catching.
''This bridal set has a value of almost £300,000. I would value the new engagement at £275,000 and the diamond wedding ring at £15,000.
''Jean-Bernard is to be congratulated for his taste - they are two
gorgeous rings and work so well as a combination.''
And Vashi believes the pieces are worth much more than the engagement ring and second ring given to Cheryl by her first husband Ashley Cole - who she divorced in 2010 amid reports of his infidelity.
The Vashi.com founder added:''Originally, Ashley Cole proposed to Cheryl with a sweet heart-shaped diamond engagement ring worth around £150,000.
''After the cheating scandal, he attempted to 'wow' her back and bought her a huge six-carat princess cut diamond ring, with a complementing dazzling yellow diamond halo setting. This set him back £160,000.''
Spencer Morrill believed he was in a relationship with the singer and that she was hiding messages for him in her songs.
Was the singer unknowingly taking counterfeit pain medication?
Roberts had left the band in 2012, due to problems with blood circulation and other health issues.
The popstar turned actress is back in the studio.
