The source told UsWeekly: "Scott hits up a lot of girls whenever he’s looking for company and has a lot of girls’ numbers.DMs girls on Instagram and leaves flirty comments. That is completely normal for him. He’s single so he’s not embarrassed for doing so. It gets their attention."

However, the insider went on to explain that despite the breakup, the socialite is unlikely to cut Rebecca out completely because he likes to remain on good terms with his ex-girlfriends.

The source added: "Scott won't cut Rebecca off completely. He likes to remain amicable with some of the girls he dates.
