Pregnant Reese Witherspoon in hospital "with complications"
The heavily pregnant 36-year-old Hollywood actress, who's married to talent agent Jim Toth, has been in and out of hospital in LA this week.
A source told website Radar Online: "Reese was actually taken to the hospital on Tuesday night with complications.
"She was released that night and then rushed back to the hospital today. At this point it looks like she might have the baby."
Reese - also mum to Ava and Deacon from her previous marriage to Ryan Phillippe
- isn't actually due until next month.
The insider added: "Reese and Jim are a little worried about having the baby so early.
"But it's close enough to her due date
that they're confident the baby will be just fine."
