Baby bump or unflattering dress? That is the question.

While in Spain to celebrate David Beckham’s last game with Real Madrid, Katie Holmes set tongues wagging after she appeared to have a bump under her clinging mini-dress.

But just days later Holmes, who is in South of France with husband Tom Cruise to attend the wedding of Australian media mogul James Packer, wore a figure-hugging cream dress that looked noticeably bump free.

Still, some sources insist she is pregnant.

According to The Sun, one said: “Katie and Tom are thrilled to be having another baby on the way. She’s glowing with happiness.”

Holmes has certainly made her intention to expand her family very clear.

When asked last month if she and Cruise would like to have more children, she replied: “Yes, definitely.”

As well as the couple’s 1-year-old daughter Suri, Cruise has two adopted children Isabella, 14, and Conner, 12 with his former wife Nicole Kidman.

Holmes has said she loves being with her family: “We’re having the best time, it’s so amazing.”

She will soon have a new neighbour to swap motherhood stories with.

When they move to California, the Beckhams will live right near the Cruises
