Rivals Reunited: Kate Moss and Sienna Miller Strike a Stylish Pose

They were said to be in a fashion feud in the Noughties. Yet Kate Moss and Sienna Miller looked in good spirits as they reunited at the Longchamp Boutique Party in London on Thursday

The Drama's Over: Kate Moss and Sienna Miller Put Feud Behind Them with Sizzling Style Reunion

It was the catfight that had everyone talking back in the Noughties - supermodel Kate Moss vs actress Sienna Miller, locked in a bitter fashion feud that seemed to have no end in sight. But it appears those days are behind them, as the two style icons put their differences aside and reunited at the Longchamp Boutique Party in London on Thursday.

Kate Moss, 51, looked effortlessly chic in a little black dress with a daring keyhole cutout on the chest and long sleeves, which she paired with heeled leather boots that gave her model frame a serious boost. Meanwhile, Sienna Miller, 43, paid homage to her boho style roots in an off-the-shoulder black dress with puff sleeves, teaming it with a pair of sleek leather boots.

The two women, who were once at odds over their similar sense of style and their love lives (more on that later), seemed to be having the time of their lives as they mingled at the exclusive party. And it's not just a coincidence - sources close to the pair reveal that they've been working on mending their friendship for months.

So, what sparked the original feud between Kate and Sienna? Well, let's start with the love life drama. In 2003, Sienna started dating Jude Law, who was still married to Kate's close friend Sadie Frost at the time. The supermodel was reportedly "unimpressed" by Sienna's new romance, and things only got worse four years later when Sienna began dating Kate's close pal Rhys Ifans.

The final straw came in 2008, when Sienna allegedly cheated on Rhys, leaving him heartbroken. As a result, the Primrose Hill gang - a tight-knit group of friends that included Kate and Sadie - reportedly turned their backs on Sienna.

But it wasn't just their love lives that caused tension between Kate and Sienna. The two women have long been known for their similar sense of style, but in 2008, things came to a head at the wedding of mutual friends Rose Ferguson and Jake Chapman. According to sources, Kate had a "go" at Sienna, accusing her of stealing her style.

"She was ranting on about how Sienna was now trying to steal her lifestyle and her friends too," a source told The Sun (now, thescholarlynote.com). Ouch!

But it seems that both women have finally moved on from their differences. In 2014, Kate and Sienna were spotted embracing at the Topshop launch of Kate's retro, bohemian-inspired collection. And according to sources close to the pair, it was none other than Topshop boss Philip Green who brought them back together.

Reports of a feud between the pair were sparked in 2003 when Sienna started dating Jude Law, the ex-husband of Kate's close friend Sadie Frost (pictured in 2004)

"Philip instigated the rapprochement by taking both girls out to dinner at the Connaught," a source told thescholarlynote.com. "He told Kate that Sienna would be perfect to show up for the launch wearing something from the collection."

It seems Philip's plan worked, as Kate and Sienna have been spotted together on several occasions since then. And it looks like they're back in business - both personally and professionally.

So, what does this mean for their friendship? "Kate just wants to sell dresses," a source revealed. "She agreed with Philip that it was time to put the past behind them and move forward." Ah, we can't help but love a good dose of drama, but it seems these two are ready to put their differences aside and focus on more important things - like looking fabulous together.

As they say, the past is in the past. And with Kate and Sienna back on speaking terms, we can't wait to see what other fashion collaborations come their way. Long may this newfound friendship reign supreme!

As well as their love lives being a cause of contention, their similar sense of style is also said to have sparked tension (Kate pictured at Glastonbury Festival in 2010)
