The Beady Eye frontman singer is reportedly ''serious'' about stealing the pair's two pet pooches, Ruby Tuesday and Brigitte Bardot, because he misses them so much and he is unable to ask the former All Saints singer to see them because they are not on speaking terms.
A source said: ''Liam is telling pals he knows someone in the SAS [Special Air Service] who will rescue them.
''He's saying they could be in and out in a flash and they won't need to abseil down the building because there are drain pipes.
''As they belong to the both of them, he thinks he has every right.
''He's missing them a lot and desperately wants to see them.
''He was serious about stealing them back.
''It's not like he can call Nicole and ask to see them -- they're definitely not on speaking terms.''
Should Liam not go through with his plan then the 41-year-old singer is expected to be locked in a custody battle with Nicole - who was left devastated this summer when it emerged Liam had fathered a child with US journalist Liza Ghorbani - over their sausage dogs when they start divorce proceedings.
A source added to The Sun newspaper: ''Given how much he's talking about them, he'll definitely be asking to share custody of them when divorce proceedings start.''
The former Oasis frontman was recently said to be missing his two canines so much he has been visiting pet shops in Primrose Hill, north London, to get his ''doggy fix''.
