Beyoncé Knowles is said to already be thinking about having a second baby.

The music superstar and her rapper husband Jay-Z welcomed Blue Ivy into the world in January.

But Star magazine claims that they are already excited about adding to their family as they want their children to be close in age.

'They see no reason to wait,' the source told the publication. 'Beyoncé has said giving birth and dropping the baby weight was far easier than she thought.'

'Everyone in their circle is saying that another baby could be on the way before you know it.'

The couple recently went for a romantic getaway to St. Barts with insiders saying they want to start trying as soon as possible.

'It took them a while to conceive Blue Ivy, so they don't want to waste another second,' the insider revealed.

'Beyoncé and Jay-Z adore being parents, and they're as hands-on as they possibly can be. Beyoncé has found a passion other than music, and it's being a mom.'

'It's in the best interests of both of them to have Beyoncé pop out another one before she goes back out on tour,' the source added. 'If she gets pregnant soon, they will be thrilled. She'll just extend her break, and next year she'll have the biggest comeback ever!'
