star Gillian Anderson, who is expecting her second child
, has opened up about her pregnancy on her personal Web site.
"I am pregnant; which I have no doubt many of you know," Anderson, 38, writes on her site's "Latest News" page. "And I am very excited. And I am very fat."
Anderson separated from her second husband, foreign correspondent Julian Ozanne, in April after 16 months of marriage. Her baby's father is businessman Mark Griffiths, Anderson's manager told PEOPLE in July.
In her Web posting, Anderson writes, "This year has not been about work at all really but about endings and beginnings and change and growth and pain and happiness and ultimately SLOWING DOWN … on a personal front. Taking stock of what is important to me, what matters, what I actually want my life to look like."
Anderson, who had a daughter, Piper, 11, while on The X-files,
writes that this pregnancy is different. "I have to say, the first time round I was oblivious to the miracle and the stages and the joy.
"I mean, honestly, I cannot remember P kicking! Was it the hours, the FX smoke, the dummies with maggots eating their eyes out? What distracted me from such an important and momentous experience!?"
Next up, Anderson will appear in The Last King of Scotland,
a drama about Ugandan dictator Idi Amin that she says is due out in September or October, and the thriller Straightheads,
due early next year.
