Alyssa Milano is expecting her second child.

The 41-year-old actress, who recently admitted she and her husband David Bugliari were ''actively trying'' to give their two-year-old son Milo a sibling, has revealed she is pregnant again.

The 'Mistresses' star announced the happy news on her blog on Friday (21.03.14), writing: ''We are so happy to share with you that Milo is going to be a big brother!''

She also shared a link to the post on Twitter, writing: ''Ahem! Click here for some BIG, HUGE, HAPPY news.''

Last month the brunette beauty joked that her husband, who is a Hollywood agent, was even taking supplements in a bid to increase her chances of getting pregnant.

She said: ''We are actively trying. David's] just chugging down ginseng [a herbal remedy believed to increase sex drive and improve erectile function in men].''

Alyssa - who shot to fame on 'Who's the Boss' when she was 11 years old - was forced to defend her post baby body after being insulted by 'Suburgatory' star Jay Mohr during a radio interview in December.

He said: ''It seems like she had a baby and said, 'I don't really give a s**t'.... I read it on her gut.''

Alyssa challenged him on Twitter after hearing the rude remarks but eventually accepted his apology.
