Britney Spears & Mother Lynne Reconciling Comes Amid Isolation After Memoir

4:20 PM PT — As if Lynne’s presence wasn’t enough proof they’re simpatico again … here she is cradling her daughter … and vice-versa.

These photos are starting to make the rounds, and they appear to show Brit and Lynne palling around during her birthday get-together. Like we said … mending fences.

Britney Spears and her mother, Lynne Spears, reunited this weekend and appear to be on the road to reconciliation … and despite their recent problems, mom seems to realize — her daughter needs her right now.

Sources with direct knowledge tell TMZ that Lynne’s drop-in for Brit’s birthday party Friday night was no coincidence … but it is indeed meaningful, especially after everything the two of them — the Spears family, at large — have experienced over the past few years.

More recently, Britney torched her immediate family members in her memoir, ‘The Woman in Me’ … and as it pertains to Lynne, she accused her throwing out precious valuables of hers — something Lynne denied.

There were also reports of Lynne selling off some of Britney’s famous clothes … but she denied that too. Of course, Britney has also suggested her mom was just as culpable for her conservatorship as her father, Jamie … and there’s been bad blood for a while there.

The two of them attempted to bury the hatchet earlier this year, pre-memoir, with Lynne flying in to L.A. to meet up with Britney and her then-husband Sam Asghari … but it was a brief chat, and it wasn’t clear whether they were on the greatest of terms at that point.

Now, we’re told Lynne and Britney are definitely in a better place … not only did Lynne swing by for the birthday bash — but our sources say they were 2 peas in a pod last night, which then turned into Lynne spending the night … and also, hanging out with Brit today.

As far as what, exactly, spurred this latest coming-together … our sources tell us Britney’s incredibly isolated and alone right now — especially after divorcing Sam. We’re told she has almost no friends or confidants — and it appears Lynne recognized that.

Britney is still close with her brother, Bryan — who was also in attendance for her party Friday night — but she doesn’t see him as often. Now, there’s another person in her orbit … somebody of her own flesh and blood, no less.

It’s great to see them acting like a family again … but the same can’t be said about Britney and her dad/sister, whom she has not been seen with for several years. By all accounts, she doesn’t talk to them … although there have been signs of warming toward Jamie Lynne.

No better time than now to heal old wounds, we suppose … it is the holidays, after all.
