Over the weekend, the Daily Mirror's Sunday People tabloid reported that Middleton and Jackson planned to announce their engagement after her 30th birthday on Friday. The report claims that the pair kept their wedding plans secret for three months so as not to distract from the birth of the royal baby.
The Mirror cites unnamed "friends" of the couple as sources, so this news should be taken with a grain of salt. But royal watchers did spot the two looking cozy and in love at Wimbledon last July.
The couple have been dating for six months, according to The Guardian, after meeting last year at a London nightclub.
