Agyness Deyn's sister is thrilled with her secret marriage.

The British supermodel tied the knot with 'Friends' actor Giovanni Ribisi in a surprise ceremony last weekend and Agyness' model sister Emily took to twitter to celebrate their union.

She wrote on twitter: ''Congrats to mi sis @aggydeyn & mi new bro in-law Freakin love dem so much

The 37-year-old actor's representative confirmed their marriage yesterday, saying: ''Agyness Deyn and Giovanni Ribisi quietly married in Los Angeles over the weekend.''

According to Crown City News, the pair were spotted ''passionately kissing'' while standing in line at the Los Angeles County Registrar's office and confirmed they were planning to wed when quizzed by a reporter.

They also said they had been dating ''for a while''.

News of the wedding may come as a shock as it was only in March that 29-year-old Agyness - who split from The Paddingtons rocker Josh Hubbard in 2008 after four years of dating - said she was ''all alone''.

She said: ''I'm all alone. There has been no man in my life for several months now and although it would be nice to have a boyfriend, I can't just settle for anybody.''

Scientologist Giovanni - who can next be seen in 'TED' - has a 14-year-old daughter Lucia from his four-year marriage to Mariah O'Brien, who he divorced in 2001.
