Robin Thicke was blindsided when wife Paula Patton, with whom the crooner was involved for two decades, dumped him and said she wanted a divorce last month. While the actress seemed steadfast and firm about the split, rumor has it she may be softening towards Thicke.

Post-split, the 'Blurred Lines' singer publicly declared that he wanted her back and dedicated songs to her on his current tour.

Sources close to the pair told TMZ that they've never stopped talking and are in constant touch while he is on the road.

While at first Patton was adamant about the big "D," insiders say that she is open to giving it another go if the blue-eyed soul star convinces her he can make the marriage work. Their interaction remains smooth and cordial, according to the sources.

Patton has yet to hire a lawyer and that's not on the top of her to-do list, either, which bodes well for Thicke, who appears desperate for a reconciliation.

Those onstage proclamations of love have not melted the chill off her heart; his actions towards their son Julian, however, have. Thicke is seeing Julian whenever he can and remains in touch while on the road.

Hmmm… if anyone can turn on the charm and change her mind, it's Thicke. He just needs to remain on the straight and narrow.
