There was just a small hint of her baby bump in the actress's loose-fitting dress.

Pregnancy rumours have been surrounding Barrymore since February when she was photographed carrying a sonogram.

The couple confirmed their engagement in January after Kopelman got down on one knee over Christmas in Idaho.

The pair had been dating for 11 months when they got engaged and are planning to wed this summer.

Speaking about wedding plans earlier
this year, she gushed: 'The thing that I think we’re the most excited
about is … this will be such a nice year to do wonderful things
together.

'We like to spend time with our friends anyway, so on the auspices of this kind of a celebration, even more heightened and wonderful. What a great adventure.'

Former E.T. child star Drew has not had much luck in the marriage stakes thus far.

She wed Welsh bar owner Jeremy Thomas in March 1994 – but split just a month later.

She went on to marry Canadian comic Tom Green in July 2001, it was all over just five months later.

Some of her more recent squeezes include actor Justin Long and The Strokes drummer Fabrizio Moretti, who she dated for five years.

She was engaged to Leland Hayward when she was just 16, and the following year was engaged to musician Jamie Walters – but neither resulted in marriage.
