Former £1,200-a-night escort Jenny, who bedded Wayne Rooney while his missus was expecting, is six months gone.
Now the 23-year-old, who admits sleeping with more than 100 men, is taking a DNA test to make sure of the identity of the father.
Jenny said Man Utd star Rooney would not be “concerned in the slightest” about the baby girl — due on Christmas Day.
But she added: “Quite a few men will be trying to work out if it is them.”
A source said Jenny believed the dad was one of FIVE possible candidates.
Her past conquests include Rooney’s Man City rival Mario Balotelli and reality TV dwarf Josh Bennett.
Other blokes linked to her include Geordie Shore hunk Gaz Beadle and Towie’s Tom Pearce, with whom she was snapped partying.
She was also rumoured to be regularly hooking up with “a lad from Manchester” around the time the baby was conceived.
The ex-convent schoolgirl said it “made her laugh” to think different men would be frantically trying to decide if they were responsible.
She said: “If they work it out they’ll know. Mario and Josh might be worried — they will have to do the maths.”
Jenny started feeling “bloated” two months ago and did a pregnancy test, which was negative.
But when she kept growing larger she went to her GP — and was stunned to be given the news.
The source added: “There will be a few worried men around.”
In 2010 Jenny and ex-pal Helen Wood had a threesome with Rooney while wife Coleen was pregnant with son Kai.
