'Jen can see there are sparks there. She's telling friends that this was a very tacky maneuver, since she and Justin are going through a divorce,' a source spills to the publication.
'He could have waited a few more months before flaunting a famous new girlfriend.'
Still trying to reconcile the fact that Brad instantly took up with Angelina, Jen is reportedly livid that she might have to deal with a new scandal with an ex-husband.
'This has brought back unpleasant memories of Brad and Angelina, and Jen just wants a clear sense of the timeline between Justin and Emma,' says the source, who adds that Jen is especially suspicious of Justin's attempts to keep his rendezvous on the down-low.
Star's source also adds, 'She accepts that they tried and it didn't work - but she isn't willing to accept another bout of humiliation from a husband.'
'She doesn't want him back, she just want him to be straight with her.
'It's a huge betrayal,' the source finishes.
Jen and Justin are yet to respond to Star's report.
