Jessica Alba and Mariah Carey each tied the knot in pretty low-key weddings, but are there bigger celebrations in store for them?

Jess' brother Josh has hinted that his sis is planning a second ceremony later this year to celebrate her nuptials with family and friends. No one was invited to her real wedding on Monday to baby daddy Cash Warren in an effort to keep the affair hush-hush. In fact, Josh says he heard about the courthouse marriage from Us Weekly! He tells E! News that he was surprised because he knew "they are going to do a big ceremony later," but adds that he didn't "know any of the details yet." With a big mouth like that, we can see why!

Meanwhile, Mimi squashed rumors that she and new hubby Nick Cannon are planning a $4 million wedding ceremony in New York this summer. While they actually got hitched in the Bahamas last month, the party would allow the couple to renew their vows in front of friends and family. Mariah says she may have another ceremony, but it won't be as extravagant as reported. "4 milly? On what? Cake? LOL," she wrote in a statement to MTV.co.uk. Uh, this coming from the woman who paid $7,200 a day for an on-call hairdresser and make-up artist?
