In his most recent outing, Bradley Cooper joined his friend Kate Hudson to celebrate Leonardo DiCaprio's 48th birthday at a party in Hollywood on November 11.
The Almost Famous actress was seen being driven to the star-studded party by the Nightmare Alley actor in his posh SUV.
The lovely buddies, who have been together for over a decade, were beaming the entire time.
Bradley was spotted driving Kate to a dinner in Hollywood back in 2012 when she was still engaged to Matt Bellamy, the father of her unborn child.
That undoubtedly aroused some eyes, but any romantic conjecture was immediately dispelled.
According to Huffington Post, the two were collaborating on a theatre production at the time. Bradley and Kate have gone on several dates together since then.
Leo's celebration comes following rumours Bradley has reconciled with his former Irina Shayk after they were recently seen out on a couple outings.
According to a source who spoke to Page Six, the ex-couple, who already have a 5-year-old daughter named Lea, are even trying to have another child together.
Fans are aware that it wouldn't come as much of a surprise to have another child after the couple reignited reconciliation speculations when they were sighted together in New York City at a fashion show.
Without mentioning him by name, Gomez talked in her movie about her romance with Justin Bieber and their very public breakup.
