Halle Berry is pregnant again.

The 43-year-old actress is said to be three months along with her second child with her model partner Gabriel Aubry - with who she already has a 17-month-old daughter, Nahla.

A source said: "Halle is overjoyed. She's just ecstatic to be pregnant again. She wasn't sure if she'd have another baby, so she's very happy!"

Halle struggled to conceive Nahla - she took over 30 pregnancy tests before one confirmed she was to become a mother - and it is believed she underwent artificial insemination to get pregnant this time

The source added to Life and Style Weekly magazine: "The first time, she eventually conceived through in vitro fertilization (IVF). This time, the baby was conceived through artificial insemination."

When pregnant with Nahla, Halle admitted she and Gabriel were keen to have at least two children.

She said: "We always talked about having two. Whether or not we'll actually make that happen is left to be seen, but that would be our intent. That's for sure."

Halle's representative is yet to comment on the reports.

The actress is not the only celebrity who is expanding her brood.

Mark Wahlberg is believed to be becoming a father again after his wife Rhea Durham - with who he already has three kids - was spotted with an apparent baby bump.

Mark has previously admitted he would like a large family, saying: "When the kids are good, we want eight or nine!"
