Lopez pregnant with her first child?

Jennifer Lopez has reportedly had an ultrasound scan revealing that she is pregnant with her first child by her husband Marc Anthony.

The singer/actress has been trying for a baby with Anthony for the last two years and she has reportedly undergone in vitro fertilisation to help her out.

A source told In Touch magazine : "The test calculated that she was about 12 weeks pregnant."

Close friends of the stars have also alleged that doctors think that J.Lo could be expecting twins with her third husband, who already has three children from previous partners. The pair married in 2004.

Neither Lopez nor Anthony have confirmed the news or whether it will interfere with their joint tour which is due to begin in November.
